Server crashing with signal 11 (core dumped)

Hi,

litespeed server is crashing often (may be due to a single domain) in our shared hosting environment.

1. Is it possible to find out the domain/website which is causing the crash?
2. How to solve this problem? (We have around 100 domains hosted on shared environment)

Please check the core dump issue.
