Crash!!! Handling signal 11 on import to table with multi64 field

Open patrikhermansson opened this issue 2 years ago • 4 comments

Doing an import to a table which uses columnar Manticore crashes with message Crash!!! Handling signal 11. (SIGSEGV) No further details in query log and it is not related to a specific document. The import always crashes after a few seconds however. I have imported much larger tables with success.

The issue seems to be related to a multi64 field (which i did not use with the successful tables). When i set engine='rowwise' on this field, the issue goes away and i can import the full table.

Global config options on the table are: engine='columnar' dict='keywords' expand_keywords='1' index_exact_words='1' min_infix_len='3'

Im on the latest Manticore release 6.0.4 and it's in docker.

Thanks for reporting. We are now investigating a similar issue, but with multi, not multi64. I hope it's the same one. I'll let you know when that issue is solved.

That's great! Thanks for your work.

I should also add that after the crash, Manticore fails to start again. Getting a Signal 11 soon after start up despite despite there not being any connections. Have to delete indexes and start over.

The issue I meant is https://github.com/manticoresoftware/columnar/issues/20.

@patrikhermansson This is bad and unfortunately can't be reproduced in the above issue. If you can reproduce it, please do and provide more details.

I've been also told by the team this issue might have been already fixed, so you may want to check out the latest dev version https://mnt.cr/nightly
