Startink up the docker with default parameters, Stirling idling, still uses unreasonable amount of CPU and memory.
18% spikes while doing absolutely nothing:

Saw someone else report this recently about file cleanups
Seems something wrong with that logic
Will investigate
In meantime if you go to settings.yml for tmp file cleanup change the time to be a much higher number should remove those spikes

I wouldn't expect that every 5 seconds though.. might be a different issue.. will check further and let you knw

This is still happening. I opened my Unraid NAS and saw that all cores were at 100%. I checked htop and saw tons of libreoffice processes. The load average on the server was 37 37 37 -- a constant 100%, not just spikes. I shut down the docker container while this was happening.

To be clear, I have not used or configured the app at all since installing it. Never even loaded the webpage. I have just not gotten around to it yet.

Here are some of the last logs after shutdown. Thank you!

Same issue exactly that broke my setup right now, 157 spawned s.office process, with no reason at all (idle since container started, no action at all... log look like exactly as above comment).

As for the issue every 5 seconds of OP's issue, I think it's the healthcheck.

[Frooodle]

Will check this today

[Frooodle]

Assume the office spawning is different issue to the above but both worth investigating

[Frooodle]

Found the issue with both, will be included in next release whenever we get that out!

[Frooodle]

Should be better now in 2.9.0 but i have another update coming soon to further imrpove, but let me know if you see a improvement in 2.9.0

[plind-junior]

@Frooodle Is this issue resolved? Or should I tackle this one?

[Frooodle]

If you can find and address additional concerns with this go ahead! Always welcome and would be higher priority
