Module Cache 500 error

[stickyzzz]

Hi all,

Occasionally I am getting this 500 error: [Module:Cache]handlerProcess return 500 due to cant alloc memory.

Any idea what's causing it? Sever is Ubuntu 20.04.1, runnig OpenLiteSpeed 1.7.12 and CyberPanel 2.1

Thanks!

Maybe you can run `top` or `free -h` command to check if the service run out of memory.

I'm running monit to monitor ram and swap usage and it didn't seem to be running out of memory:
Swap usage limit If greater than 25.0% then alert
Memory usage limit If greater than 75.0% then alert

I increased the php memory_limit to 256M, though I don't think it's related to the issue.
I'm still getting the error in the logs after the memory_limit change.

Any other ideas?
