When starting Identity Portal, the logs shows a lot of lines concerning JGroup:
WARN org.jgroups.protocols.pbcast.GMS - SOMESERVER-53591: JOIN(SOMESEREVER-53591) sent to SOMESERVER-37379 timed out (after 3000 ms), on try 6
The portal does not come up properly and is not available
This sometimes happens in a clustering environment.
The error is benign. Waiting for 10-15 minutes will ensure that the portal is up and runinng.
An alternative is to clean the JGROUPING table.
