Parity-ethereum: 2.7.2 on Windows just terminating

[esocode]

• Parity Ethereum version: 2.7.2
• Operating system: Windows
• Installation: parity.exe
• Fully synchronized: both
• Network: ethereum
• Restarted: yes

I downloaded 2.7.2 for Windows today but it always terminates shortly after start, without syncing and without any error message. Even debug output shows nothing peculiar. Tried on two different machines, with and without existing sync. The console output before termination is just the regular info:

I had to revert to 2.5.13 which works fine.

@esocode

Could you monitor your memory usage? My best guess is that you ran out of memory.

[esocode]

No, memory is not an issue. One of the machines has 32G (>16 available). And parity fails fast, just prints the console output and then exits. I have also removed any existing config and chain files but that doesn't help either.

[esocode]

Just tried a third machine (with 32G) which had never run parity before with the same effect. Could only be some network problem but as said there's nothing even in the debug log. And 2.5.13 runs without problems. The only error mentioned in the debug log is the following:

2020-02-12 12:26:43   DEBUG ethcore_network_devp2p::ip_utils  IP request error: Request Error. Invalid response from gateway: <?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<s:Body>
<u:GetExternalIPAddressResponse xmlns:u="urn:schemas-upnp-org:service:WANIPConnection:1">
<NewExternalIPAddress></NewExternalIPAddress>
</u:GetExternalIPAddressResponse>
</s:Body>
</s:Envelope>

But I assume that is not critical as it is not mentioned outside debug logs.

I can repeat this. It fails very quickly at startup.
This is a regression from 2.6.8.
I have tried with the following flags, all to no effect: --no-jsonrpc, --no-persistent-txqueue, --no-secretstore, --no-ipc, --no-ws, --nat=none, mode=offline.

Interestingly issuing a command works: db kill, account list etc. Using other chains seem to work fine, I tried: --chain=goerli and kovan, rinkeby, ropsten and classic. All work.

@esocode I don't have a fix for you (yet) but I do have a workaround: if you specify the spec file for mainnet with --chain it seems to work. The file you need is here and the full command would look something like parity.exe --chain=c:\path\to\foundation.json.

[esocode]

Thanks, with this parameter parity doesn't terminate and starts synching.

[dvdplm]

@esocode What windows version(s) did the machines run where you saw this on? I can repeat the problem on my Windows 10 Version 1809 (OS Build 17763.1039) box, but on Windows 10 Version 1903 (OS Build 18362.30) it works fine. It would be great to have more info.

In case you don't know how to show the exact build, hit Win + r and then type winver and run the utility; a small window will pop up with the exact version and build number.

[esocode]

All 3 machines are up-to-date, running the latest build 1909-18363.657. This is the latest patch from this week and I noticed the problem with the previous version, but it persists.

[dvdplm]

Hi @esocode, do you think you could try this build on your system?

parity.exe.zip

[esocode]

Yeah, that version works as it should, syncs without any extra parameters.
