@KarnikJain this is very old version (IIRC the one that was latest on the day i joined the project).
besides that, for some reason the crash report is missing a stack trace part, so i don't really know where it crashed, and i can't check if that bug was fixed already or not.

what i do see is that CURRENT CLIENT INFO shows that we're probably running BGSAVE now (although i'm not sure if there was some bug in that version which makes this information a lie).

BGSAVE doesn't actually do much (before calling fork(), which means the chances for it to crash are low.

sadly i don't think anyone can help except suggest that you upgrade to a more recent version.

@oranagra Thank you for the response. Did we have such cases in past, where Redis-Server getting Zombie/defunct and redis-server.log showing Crash like I mentioned in my o/p? tried forum but no clear clue yet.
