Cause

This message is logged by Jira as soon as it detects that one thread uses more than one connection to its database.

Resolution

There is no workaround as this a normal use case with Elements Connect which may take up to two connections by a thread. Usually, the duration of this operation is very short and should not have any significant impact on your instance.
