[self-solved]LSWS 4.0.17 and "hanging processes"
Hi, my LSWS is restarted everyday by cPanel when it is needed to process logs, as you know this is how it needs to be done according to cPanel. Lately I noticed increase in memory usage and I found out I got lot of old processes which are not killed properly by graceful restart and if I continue like this in few weeks I will ran out of memory.
This is probably bug, so I posted this topic here and please let me know what can I do do ensure this doesn't happen anymore.

what's result of pstree -p
if lsphp5 process has no parent, then it's a runaway process, just kill it.
you can strace the runaway process, what it is doing. a bug php script may cause dead lock and waiting for mutex etc forever.

this is the problem ... most likely it's related to bug in php script. we can login your server to investigate, in case it really a bug of lsphp. |

This is trace result of this "hanging" processes:
strace -p 9492
Process 9492 attached - interrupt to quit
futex(0x4a280c, FUTEX_WAIT, 2, NULL <unfinished ...>
Process 9492 detached
root[~]# strace -p 10231
Process 10231 attached - interrupt to quit
futex(0xaf8140, FUTEX_WAIT, 2, NULL <unfinished ...>
Process 10231 detached
And all other hanging processes to that script are the same, I could probably try to kill them and when my server will not be so busy to restart mysql also, it hasn't been restarted for 4 months.

I'd give a quick guess: xcache caused the problem. can you try disable xcache and see if the issue still exist.
