I obfuscated the queries.
We are enterprise customers but I unable to login to https://my.vertica.com using my work email address, password resets do not seem to help, I have requested a new account using a different email address. My posts to https://community.vertica.com/vertica are also failing at the point of preview.

Thanks,

Re: SEGV_ACCERR in GroupByHash running v7.0.0-1

Post by thatsafunnyname » Mon Jul 21, 2014 9:33 am

This was resolved (for us) in:

Resolved issues in Vertica 7.0.1-2
VER-31016 (Execution Engine) Certain queries involving Group By where the data was partially sorted could result in a server crash. This issue has been resolved.
