Condition or Error
The trepctl status command hangs at the end of the output after a "cannot fork" error.
This can be caused by THL corruption on the slave.
This can be also be caused by an Out-Of-Memory condition in either the replicator or in the OS itself.
You can recreate the THL files on the slave(s) ONLY. This can be achieved by deleting the existing THL files, which will cause the slave replicator to download all of the THL data from the master again:
shell> replicator stop shell> cd /opt/continuent shell> mv thl thl.old; shell> mkdir thl shell> replicator start shell> trepctl status
