Preflight Checklist

• [x] I have searched DeFiChain’s Github Issue Page and none matches my issue
• [x] I have read through How To Submit Issues for DeFi App

Issue Details

• DeFi App Version:
  
  
  
  • 2.1.11
  
  
• Previous DeFi App Version:
  
  
  
  • 2.1.4
  
  
• Operating System:
  
  
  
  • (Mac OS 10.13.6) (see Picture), with 360 GB free Disk-Space
  
  

Screenshot(s) / screen recording(s) of issue

Actual Behavior

Please provide steps on how to reproduce the issue:

1. I remove the 2.1.4 App out the Aplication Folder.

2. I Copy 2.1.11 to the Aplication Folder

3. I Start the App.

4. immediately started loading the blockchain, quickly and everything seemed ok.

5. At 99.88% it stopped (see Picture) and it no longer continued to load the Blockchain. My Mac became very slow at this Moment. I could hardly change windows or type anything. When i typed, the signs came as if in time. Always the spinning ball. The download monitor showed no download (see Pictures), but sometimes a lot of uploads.
   I left the Mac running for 2 hours without success.
   However, the wallets were displayed with the data already loaded from the BlockChain. After clicking around in the program, white screen. Then I shot down the program. Mac still slow but a little less bad. It seems that the Mac is still weighing something even though the app is no longer running. after about one to two hours, the mac is almost back to normal. But it goes faster if I do a restart.

6. I already had this problem with 2.1.4. Sometimes it worked, and sometimes that's exactly what happened. Sometimes it was suddenly 100% synced after all, and then the Mac ran normally again.

7. i have uploaded the Log Files

Expected Behavior

I've struggled with different versions of this app for many hours now. Version 2.1.4 worked best for me, but also with many Bugs. But I am sure that at some point you will get the app perfect and I would like to thank you very much for your work!

I have similar issue with this version on windows 8. did not have that problem on previous version.
Slow down and lag around 99.7%.
Sucking a lot of memory.
I included a screenshot of memory consumption in the logs.

Hi @Capswiss , thanks for the feedback. In the future, when updating the app, you can do in internally in the app or download from https://defichain.com/downloads/. and replace your current app. Your app syncs till 99%+ then it get stuck and there's no error shown on the app screen? Logs well received, please give us time to investigate.

Hi @arnaudom , thanks for the feedback, is there any error shown on the app screen?Logs well received, please give us time to investigate.

[arnaudom]

No, there is no error message displayed.
I noticed it hanged for quite some time (maybe 30mn or more) on block 590687 with memory surge and once it passed that it continued to sync up to 100% at normal rate.

[Capswiss]

@izzycsy Thank you for your hint. I usually do the update the way you show it. However, since there were often more new problems with the updates, I wanted to keep the old version, so I removed it from the program folder first. The old version 2.1.4 worked for me at least partially.

And no, there is no error message displayed. In any case, I didn't see any. Many thanks for your Help and Work!

Hi, since today i get the same issue, sync stops at 99,95% @ version 2.1.12

What is wrong with DEFI APP? Mine will not sync either. Please help!

[izzycsy]

Hi @Capswiss I understand, I do not recommend installing older version for your safety and security, our team is constantly working on improving the app and solving its issues. We regularly do releases, so if you are not in a big hurry I would suggest staying on the latest version and wait for a fix.

Hi @cherryactiveo2 @oh-johnny @cRuuZaR @Jacobsieler8888, thanks for your feedback, please give us time to investigate this.

Hi @Capswiss @arnaudom @cherryactiveo2 @oh-johnny @cRuuZaR @Jacobsieler8888 , update v2.1.13 is out.
Do give a thumbs up to this comment if your issue has been resolved, otherwise, provide new information (include screenshots) and app logs. Thank you.

[dieterich-m]

If not already mentioned somewhere, the same issue also applies to the Win App (Win 10).

I managed to sync 100% with latest version.
It still consumes a lot of memory and even more after full sync, up to 10kMb.
Then close the application and tried to reopen but it loops forever on splash screen. Have surge of memory use memory use (more than 11kMb); computer freeze a a certain point and have to shut down.
Can't use.

All ok here with 2.1.13 👍🏽

Do you update the app for Win as well: #325

Finally tried to downgrade to 2.1.12 then 2.1.11. I had same problem, Looping on splash screen with high memory use then end-up freezing my PC.
My next procedure, under v. 2.1.11: closed app, kill all app processes running in background, deleted all blockchain data folders.
The app opened and started sync again.

Hi @INQB1 , could you send your app logs here please?

[INQB1]

It works for me now but for syncing I have to close all other apps and free memory (RAM and disk). Syncing
28JAN2021_applog_v2.1.13.log
seems to be done entirely in RAM memory.
Hence with the growing size of the blockchain it seems to need more and more every day. Yesterday, for me, it peaked at 18.5GB for a short moment at around 99.7%, and then completed with 10.5GB held in memory. I then need to close and restart the app to free that memory for it to come down to the operational level at about 450MB.

I believe soon, most computers won’t be able to handle it unless they’re loaded with extensive amounts of memory (greater than 32GB) or take ages with disk swapping.

[INQB1]

If the computer isn't equipped with enough memory, what some people do as a work around (until it's fixed) is to kill the app in between, say when it reaches 5GB of memory usage, and restart the app to resume with fresh memory. The app then continues to sync from where it was when it was stopped (process killed). Not beautiful, but it seems to work for now.

[INQB1]

For me, the memory issues pertained to all versions: v2.1.11, v2.1.12, v2.1.13
I'm now on v2.1.13 and the memory part works fine. I now struggle with a different issue, but that's not for this thread (txn-mempool-conflict (code 18)).

Not always, it happened many times to me where is starts over from 0 after killing.
At least in my configuration windows 8 / 16Gb

[izzycsy]

Hi @INQB1 , thanks for the feedback and app log. May I know what operating system you're using? if possible can you send your binary log & app config? It'll help provide more insight during investigation. Thank you.

Hi @arnaudom , well noted, the team is looking into it.

I don't think 8/16GB is enough. Deducting what the OS and system needs, there's not enough left and I wouldn't be surprised if the app sync runs into issues already at around 5GB mem usage.

[bvbfan]

This is another issue, 1GiB should be normal usage of the node.

Hi @INQB1 , the team reviewed your logs, it seems that the issue you're facing could be due to the block being stalled at block 597924 yesterday, which can cause the node to disconnect, hence not a ram issue. The solution to this is wait for the block to sync to 100% or try Reindex Option in Settings. If Reindex option does not work, you may reopen this issue, kindly send screenshots / app logs.

Hi @arnaudom , currently it seems that some windows-users are facing the issue Windows: sync stops at 99%+ > node is disconnected. Take a screenshot of your activity monitor and send it in that thread — attached is an example.

Here it is, but right now I am back on v2.1.11 and everything runs fine after I downgraded and reset all data.

Hi Bella

The root cause of the issue might be here: https://www.reddit.com/r/defiblockchain/comments/l765tb/fix_for_ram_bug_and_corrupt_blockchain/
Great troubleshoot from Kracht (Sp0nde on reddit).
Please share with developers.

Thx
