How to investigate a PANIC



I had a node go down today and am not able to find much info on why.


The vertica.log says:


2016-10-27 13:23:11.454 Init Session:0x7fc03401e080 [Main] <INFO> Handling signal: 11
2016-10-27 13:23:11.622 Init Session:0x7fc03401e080 [Main] <PANIC> Received fatal signal SIGSEGV.
2016-10-27 13:23:11.622 Init Session:0x7fc03401e080 [Main] <PANIC> Info: si_code: 1, si_pid: -335544320, si_uid: 32693, si_addr: 0x7fb5ec000000


And the next lines are from the restart...


How can I investigate what went wrong?
