Description

When trying to move sessions to another cluster (i.e. using CONTROL MOVE SESSION or CONTROL MOVE ALL SESSIONS), the statement may rarely hang due to a race condition. This can be noticed when the statement executes much longer than expected (e.g. much longer than the WAIT TIMEOUT, if specified).

Workaround

As a workaround, the CONTROL MOVE statement can be killed and restarted.

Fix

The issue will be fixed such that the CONTROL MOVE statement does not hang.
