SIGSEGV in java process in docker container

Question

I am getting SIGSEGV error from my jvm process and not able to find out what's causing it. Here's the brief error:

siginfo: si_signo: 11 (SIGSEGV), si_code: 0 (SI_USER)

This means a kill() was issued. This is not a JVM issue. Something is killing your process deliberately. Probably due to running out of memory.
