Markus Schuch commented on CONNECTORS-1581:
-------------------------------------------
JDBC driver is mariadb javaclient 2.3.0.
I will enable {{org.apache.manifoldcf.db}} debug logging to see which job ids
are involved.
What is the impact of this error happening in the "set priority thread"?
The exception is logged several times but then it stops and startup seems to
complete without further problems.
We didn't see any problems so far.
