Error with MemSQL 6.8.1 - Failed reading object file


I ran into an issue after updating to MemSQL 6.8.1 that was not present in earlier version of MemSQL (I believe it was 6.7.4). I am currently running 6.8.1 in a local single leaf, single MA instance. The table in question is queried using “FOR UPDATE” and that row is then locked for a minute or so before releasing. If I attempt to add a new row during that time MemSQL throws an error:
ERROR: Compilation of [INSERT INTO queue (worker_type, message, status, createtime, archive, project_id, worker_lock) VALUES (?, ?, ?, ?, ?, ?, ?)] failed. Reason: Failed reading object file.
The table itself is a rowstore, if that makes a difference.

Many thanks,


Hi @nfleming

Thanks for posting your question!

I briefly chatted with our engineering team, and this doesn’t look right to us. Do you mind submitting this to so we can take a further look and reproduce it on our end?

The more information you provide, the better (including full reproduction steps).



Will do. Writing up email now. Thanks.


Thanks! Let’s help you get this figured out :slight_smile:


For anyone else with this issue, it was resolved in 6.8.2.
