can you do what suggested in previous post:
1.force-reinstall 4.1.11 to latest version
2.stop lsws completely, then start it, not restart gracefully
and / or
to stop it completely. and use
#pstree -p | grep litespeed
to check if no litespeed process is running
this will only cause down time within 1 minute.
then start litespeed.
if still happen, please continue reporting here.
