[solved] High CPU load since 4.12 and 4.13

[sysmesh]

Hi,
I'm running litespeed enterprise 2 cores license on a i7 8 core (quad with 2 cores each) and 8gb of ram.
Server serves 8-20 requests per second max, IOstats shows 20% usages max and free gives out around 500K free normally.

Up to using 4.12 I had a CPU load of 0.1-1.2 MAX on peaks.
Since moving to 4.12 and now to 4.13 CPU load ranges from 6 to 9 (!!) on the same load.

I did a force re-install and it didn't change a thing or fix it.

Any hints/advice/idea on how to reduce the CPU load (btw - even my old apache2 didn't get that high on CPU)?

Thanks!

can you give the output of "top -c"?

I do apologize
Running top -c I realized litespeed was using the CPU in a high level but when looking into what it was running I noticed it was running a cron php call I had which seemed stuck.
I killed it and CPU load dropped.

Man do I feel silly.

I apologize at this seems to be non litespeed related and your support, as always is great!

Please delete this thread if possible.

thanks for the feedback.

let's keep the post so that benefit other users --- it's not rare which upgrade cause problems, and it's good not for this time and you've figured out the root cause of the issue.
