Memory leak in unraid-api

[JonD]

Hi,

 

Unraid RAM showed 90% while I typically sit around 55%.

Executed the command below and the biggest entry was

 

> ps aux | awk '{print $6/1024 " MB\t\t" $11}' | sort -n
[...]
2459.91 MB              /usr/local/bin/unraid-api/unraid-api

 

I killed the process and restarted it using the UI and its back to normal usage (~145.051 MB)

 

unraid version: 6.11.3 

My servers version: 2022.11.29.0742

Thanks, we'll keep an eye out for that. BTW the easiest way to restart the api is `unraid-api restart`

[JonD]

Ah thanks! that works better than killing it and i can cron this every day or so until it is fixed

PS: After one day, its up to 191.9 MB (from 145MB)

likewise here noticed it slowly increases: 

 

Uptime 16 Days

Version: 6.11.5 

my servers: 2022.11.29.0742 

 

I updated my Servers to 2023.01.23.1223 and the api seems to have stabilised, will monitor it.

Thank you for this command - useful

Yes we didn't call it out in the release notes but the current version does make some improvements here.

is this normal for unraid-api to use 73M of ram?

I'm looking at a similar situation with stdout.log.1 not-so-slowly filling up /var/log.  It seems to be set to DEBUG level logging and is not rotating despite being >10MB in size.

 

root@Unplucky:/var/log# ls -alh unraid-api/
total 37M
drw-r--r--  2 root root 100 Jan 11 04:40 ./
drwxr-xr-x 13 root root 780 Jan 11 03:00 ../
-rw-------  1 root root 146 Jan  3 12:40 stderr.log
-rw-------  1 root root   0 Jan 11 04:40 stdout.log
-rw-------  1 root root 37M Jan 12 08:05 stdout.log.1

 

Also interesting that it's writing to ".1" and not the standard named file.

[Mat W]

Well, I think updating unraid-api has resolved my issue.  After the update it wrote INFO level logs into stdout.log and hasn't written anything more to stdout.log.1.  I'll continue to monitor but I believe that "fixed" it.

root@Unplucky:/var/log/unraid-api# ls -alh
total 37M
drw-r--r--  2 root root  100 Jan 11 04:40 ./
drwxr-xr-x 13 root root  780 Jan 12 08:11 ../
-rw-------  1 root root  146 Jan  3 12:40 stderr.log
-rw-------  1 root root 2.8K Jan 12 08:11 stdout.log
-rw-------  1 root root  37M Jan 12 08:11 stdout.log.1
