- Version: v4.8.4
- Platform:
Linux <hostname> 2.6.32-504.el6.x86_64 #1 SMP Wed Oct 15 04:27:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Opening this early but so far I have neither a good reproduction nor any hint of the root cause.
After trying to roll out node v4.8.4 on some of our hosts, we are seeing occasional process crashes:
Jul 13 20:32:04 <hostname> kernel: node[14507]: segfault at 3b5f2eb00504 ip 0000000000aed6c1 sp 00007fffb02b1eb0 error 4 in node[400000+12e5000]
This happened using the official binary distribution (https://nodejs.org/dist/v4.8.4/v4.8.4-linux-x64.tar.gz).
This didn't happen with node v4.6.1 (a rollback to this version made the crashes go away).

I'm also trying to get a core dump to dig a bit deeper.

I've also got a couple of core dumps now that we collected over night:

End of assembler dump.
Thanks. It's failing on the IsUndefined() or IsTheHole() check on this line in objects.cc (warning: big file), presumably element is not a valid pointer (although it looks like one, its LSB is tagged.)
Just to be sure, what does p/x *(long*)0x22cc054b3590 print?
bnoordhuis
on 17 Jul 2017
Yep, that address isn't a thing:
(gdb) p/x *(long*)0x22cc054b3590
Cannot access memory at address 0x22cc054b3590
P.S.: Thanks a lot for the help in looking into this! :) We've seen this issue in multiple applications now and - afaik - they don't share any native modules. But I still don't have any way of reproducing it reliably (other than running a bunch of instances and waiting 1-2 hours).

No problem, happy to help. Can you post the output of info registers and disassemble for the other core dumps? Hopefully that provides some more insight.

End of assembler dump.
Looks like they are all the same issue: pointers that look like valid heap object pointers but aren't. Something puts the heap in an inconsistent state but hard to say what.

I was afraid that was the answer. Is there any value in rolling out a debug build of node to some canary hosts or is it unlikely to provide more insights? Otherwise I could try to at least narrow it down a bit (somewhere in v4.6.1...v4.8.4 is pretty broad).

Sounds like a similar issue has been reported for v4.8.0: https://github.com/nodejs/node/issues/11606
Commonality: Both use express. But that's hardly saying anything for node web apps.

We get such bug reports frequently but nine times out of ten it's caused by a native add-on.
A debug build would help, those usually catch bugs closer to the source.
bnoordhuis

Just checked - the app(s) in question don't contain any .node files, including in their dependency tree. So I don't think it's a native add-on in this case.
We'll roll out a debug build and see what we get from that.

End of assembler dump.
Added some info extracted from debug build core dumps. Let me know if you'd want me to look up anything else in there. It took some time getting a working custom build into our infrastructure so I'm only ~90% sure it will perfectly reproduce the issue (e.g. it links against different c++ runtime library versions). But the stack looks fairly familiar (ProcessWeakCollections) so I'd say that's a good sign.

@jkrems would you be able to bisect by testing some of the other Semver-Minor releases and see if we can narrow this down a bit

@MylesBorins Will definitely try. The problem is mostly that I don't have good/fast test cases. My only way to reproduce right now is "roll out to canary hosts, wait hours, see what happens". Which is rather time consuming...
- [x] v4.6.1 - GOOD (assumed) - verifying
- [x] v4.6.2 - BAD
- [x] v4.7.0 - BAD
- [ ] v4.7.1 / v4.7.2 (same version)
- [ ] v4.7.3
- [x] v4.8.0 - BAD
- [ ] v4.8.1
- [ ] v4.8.2
- [ ] v4.8.3
- [x] v4.8.4 - BAD

Alright, 5 hours in and v4.6.1 doesn't show any segfaults. So afaict the issue starts already in v4.6.2. I will keep monitoring for the rest of the day but so far this is where I'm at:
- All 5 services that tried to deploy using v4.8.4 saw these segfaults, none of them includes compiled/native modules at runtime. They all are stable on v4.6.1 w/o any code changes.
- All services running similar code on v6.11.1 are fine and aren't showing any segfaults.
- After running one of the five for a few hours (5+ each), we've seen at least one segfault on v4.8.4, v4.8.0, v4.7.0, v4.6.2. To make sure these weren't other, unrelated issues, I took another core dump once we reached v4.6.2. The error was identical (crashed in
ProcessWeakCollections). - Finally, I verified that our existing v4.6.1 package was built using the same process I used for the other versions.
diff -rshowed no differences. The content also matches the official linux-x64 download tar.gz from the node website (just repackaged with a different root directory).
Note: We're currently working around this by more aggressively pushing teams to adopt node 6. But I'll try to keep some node 4 running somewhere until we either give up or figured out what's going on here.

One of the devs on that first lucky service (<insert Github handle here>) had a look at https://github.com/nodejs/node/compare/v4.6.1...v4.6.2 and found this one: https://github.com/nodejs/node/commit/2d07fd71ee391d099e2f19e85455be6a718c27c9. The combination of "weak collection" and "GC" sounds pretty suspicious but I didn't look more closely yet.

That sounds very plausible. @matthewloring @ofrobots Ideas? This seems to have been introduced by #7689.

@jkrems as you able to test with Node 6.x at all? It would be quite useful to know if the crash exists there or not.
/cc @mlippautz @hannespayer any ideas about the crashes in GC and whether the back-ported bug fix might have some issues on V8 4.5?

We rolled out the same stack on node 6 (by now including the very service where we saw these crashes initially). None of the services on node 6 (most on 6.11.1 now) are seeing segfaults.

The Meteor project is running into this same exact problem on Node.js 4.8.4 though I've bisected it down to the exact commit that @jkrems had identified above (https://github.com/nodejs/node/commit/2d07fd71ee391d099e2f19e85455be6a718c27c9), which landed in 4.6.2.
Though it's not 100% reproducible, it's a relatively easy numbers game and happens at least once out of every 4 runs in our CI. If you check this CircleCI build history you can see me toggling back and forth between Node 4.6.1 and Node 4.6.2 and the problem comes and goes (each entry on that page is representative of four containers running the same build, but at least one of the four containers fails each time thus failing the entire build). I can't put my finger on exactly what we're doing which is pronouncing the problem, but it's seemingly a garbage collection bug and thus prone to varied behavior.
Looking a bit deeper, the commit that introduced the issue (again, https://github.com/nodejs/node/commit/2d07fd71ee391d099e2f19e85455be6a718c27c9) was intended to be a backport of https://github.com/v8/v8/commit/e093a04. However, that commit was reverted (automatically, I think?) via https://github.com/v8/v8/commit/5f5a3282d4b21eb0800f1d1af85926670ba0d904 because "Speculative revert. Suspect for gc stress crashes". The re-land (seen in https://github.com/v8/v8/commit/09db540) on master didn't re-introduce the reverted commit (5f5a328), but I'm not sure I see the net-change of those commits reflected the same way in this back-port in 2d07fd71ee391d099e2f19e85455be6a718c27c9, however I'm far from an expert in this repo.
@jeisinger, you haven't been looped into this yet, but as the original PR author and someone who has worked on this code a fair bit, any ideas?

For what it's worth, when branched off the v4.6.2 tag, if I revert https://github.com/nodejs/node/commit/2d07fd71ee391d099e2f19e85455be6a718c27c9 (as I did in https://github.com/abernix/node/commit/49d20c5330df5a1ffe224d25f543df904849a31f) and apply https://github.com/abernix/node/commit/7841772b73da31487066f6d1bb43b1bc29b04c48 instead (which I believe is more to the letter of the original commits), I can't reproduce this SIGSEGV anymore. Additionally, the reproduction for https://github.com/nodejs/node/issues/6180 (which 2d07fd71ee391d099e2f19e85455be6a718c27c9 was purported to fix) doesn't OOM, though it also doesn't OOM with the commit reverted, so perhaps it's been fixed via other means as well (for example, e1f12fb358b833ba212bc88fe7a2e1c5a8ec22b3).
Same success story if I apply the same order of changes onto v4.8.4 (i.e. https://github.com/abernix/node/commit/f4c4c08878d2612ad46e4d035d7b15f243e4bec2 + https://github.com/abernix/node/commit/daccbf030a1b39319f9b2eb84193e47896a5c45b).
Thoughts?

@abernix could you please submit a PR that reverts 2d07fd7 and applies abernix/node@7841772 (please follow the commit guidelines for V8 changes)
we can get that reviewed and landed and cut another 4.x

@MylesBorins Done: https://github.com/nodejs/node/pull/14829. Note that the PR deviated slightly from my previous suggestion to apply https://github.com/abernix/node/commit/7841772, but I think I've explained why (see CompilationCacheTable::Age vs HashTable::Rehash in that convo).
Ultimately, the MarkCompactCollector::ClearWeakCollections changes were the breaking factor, though there's no telling what randomly wiping deleted entries in CompilationCacheTable::Age instead of HashTable::Rehash might have been doing. 🤔
Either way, I've verified that the original repro/issue in https://github.com/nodejs/node/issues/6180 is still fixed.
