Hi there.

 

I am noticing that lsof is consistently using at least 25% of my CPU, which spikes to 60%. My CPU is no powerhouse understandably, is this a normal expected behavior?  

 

I have disabled the file activity plugin and also the cached directories plugin. I am unsure how to further troubleshoot this. 

 

I'm running Version 6.6.6 2018-12-01.

System Details

M/B: ASRock - FM2A85X-ITX

CPU: AMD A4-4000 APU with Radeon™ HD Graphics @ 3000

Memory: 8 GB (max. installable capacity 8 GB)

 

 

Kinda at a loss to continue troubleshooting this myself. Then again this might be normal. 

 

Regards, Ben.

Could I please have some assistance?

Try booting in safe mode.

Maybe.  Is your web browser sitting on the Dashboard page?  If so, if you navigate off that page or close the tab, does 'lsof' activity go away?  If not, could be some other plugin using that command.

Thank you for both your responses. 

 

I'll start with safe mode and check via ssh to see if I see the same behaviour. 

 

Ill then disable the plugins one at a time and hopefully will find the culprit. 

 

 

It was the file integrity plugin. I removed it and the CPU instantly dropped.

That probably means the plugin was either creating new checksums or validating the existing ones.
