CloudLinux - mod_lsapi - httpd killed by SIGSEGV

Hello, for the last 7-8 days, I believe after one of the cPanel or CloudLinux updates, we started receiving mail reports-errors, almost every minute.

I can post entire report if it will help. Not sure if this is connected but under process manager I can see:

It seems that the problem was with the mod_lsapi after update to the latest beta version everything is looking fine. In case someone else have the same problem here is the link to the solution: [abrt] ea-apache24: httpd killed by SIGSEGV
