Build error - Query error

One of the build just failed with cryptic error message that is new to me.
It failed on one of our agents which is very slow lately (virtualization), so as it is for now one time occurens I would not put weight on it.
But maybe you could take a look and see if it’s something on your side, or is it just a communication error.

Build errors:

Hi Michal,

A timeout is happening when the server is querying the database. This usually means that the database requires some maintenance. Check the size of your database tables, and then run a vacuum, reindex and/or adjust your build cleanup rules as necessary.

Just to keep you up to date, DB maintenance didn’t help much. But taking into account that one of our tables is now about 14 GB big, we decided to give the server a bit more RAM and two more cores.
That helped, haven’t seen those issues yet.
