Do you have CSF running? CSF can kill processes that it thinks are hanging. Try adding the following to you csf.ignore file if you are running CSF.
pexe:/usr/local/lsws/fcgi-bin/lsphp-*
pexe:/usr/local/lsws/bin/lshttpd.*

Thanks Jon. I'll give that a shot and wait a few days to report back.

It's a cPanel / WHM issue, and I've had it ever since the upgrade to new WHM 64 earlier last week.
I submitted them that bug and they've (apparently) fixed it in the latest version of WHM 64.0.9:

• Fixed case CPANEL-12453: Teach ApRestart to understand litespeed.

I have yet to test it on my end on two of my servers, but here's to hoping that patch covers that issue...

Serb, you're correct - I'm still getting the alerts. Temped to pull the trigger on 64.0.9, but I can wait.

So far, that update solved it... I haven't received a single alert since. And haven't had any other issues with the update, even though it's still classified as EDGE... just an FYI from my experience so far.
