All lsphp processes die - users get "no data"
We have an issue on one of our servers running Litespeed Web Server. Every so often all lsphp5 processes will die and the server effectively stops responding until they come back again.
This is on 4.2.4, it's a busy server so the debug log grows incredibly quickly (15,000 lines covers about 4s of activity). So it's hard to see if anything is going on in there, as there's no pattern to it - unless we know what to look for in the log.
There's nothing in the normal error log, nothing logged with an info, warning or error status in the log either. There's no core dumps, the main litespeed process does not die.
