Vertica Node crashed - help :(

[Chicago_vertica]

Do you have a load balancer for the cluster?
Is the crash on different node in random?

By my experience, the immediate query in the log above "Panic" may not be the culprit. A few more queries up.

I put our log below for your reference. My key words here are "fatal" and "rollback". Hope you find your pattern in the log.

Doesn't hurt to pick out one or two and ask around. Someone may recognize it. I feel it is a bug and hopefully you can point your test app to a specific node in test.

Good luck.
