High cpu utilization since update 1.25.1

Purple8

Hello,
First time publishing here

The app is waiting for production, for now there is 0 user.

Since update 1.25.1 the CPU utilization is constantly at 62% (caused by the errors i got every 2 seconds i guess).

Here's the logs i have :

Tell me if the whole log file is necessary.

I tried to restart the app, but didn't resolved my problem
If someone experienced the same problem can help me !

Thanks

joseph

@Purple8 might be worth reporting this upstream at https://github.com/paperless-ngx/paperless-ngx/issues with steps to reproduce from a fresh install . Looks like it is constantly crashing which is the reason for the increased cpu use.

Purple8

@joseph thank you, i try to do this

humptydumpty

I'm running into the same high cpu usage too. @Purple8 did you report this upstream? If so, please share the ticket number/link.

imc67

Indeed, same issue here!

joseph

@humptydumpty @imc67 is it constantly crashing with KeyError for you as well?

humptydumpty

@joseph I have the app turned off but it wasn’t crashing for me. Just high cpu usage. I knew something was off when the fan was running at full speed.

imc67

@joseph said in High cpu utilization since update 1.25.1:

@humptydumpty @imc67 is it constantly crashing with KeyError for you as well?

No it never crashed but it has 4GB for its own

humptydumpty

I kept the app running last night and the RAM has high"er" usage too. App has 2GB allocated and is using 600-700mb and 80-100% CPU when idle.

danigl

I have the same problem. Also after update.

Purple8

@humptydumpty Hi, no i did not beacause i couldn't reproduce the error after a reinstall.

nebulon

Looks like this is indeed a regression in the app itself if so many of you hit this now. I still cannot reproduce this here, has anyone already reported this as an upstream issue with paperless?

girish

To isolate the issue a bit further, can you see the output of docker stats ? Is it showing the same high CPU usage? This would eliminate any bugs in Cloudron's graph data collection and rendering.

humptydumpty

@girish I’ll check the output in an hour or so but i can physically hear my fan kick in at full speed so it can’t be just a graph issue.

humptydumpty

@girish docker stats result in screenshot, it's high alright.

girish

@humptydumpty next step would be to docker exec -it 73c74bd70aef /bin/bash (hopefully, I got the container name correct from the screenshot) and then run top and see which process is consuming so much CPU. Usually, > 100% means some process is taking one core completely.

humptydumpty

I tried to inspect the cloudron pid further, but the pid keeps changing.

humptydumpty

@girish more info..

docker logs 73c74bd70aef | grep "celery beat"

full page w/ single repeating line celery beat v5.4.0 (opalescent) is starting.

I also ran docker logs 73c74bd70aef | grep celery and saved it to a log file. I can't paste it anywhere as it's too long. Here's a sliver of the bottom portion.
