GroupWise Messenger 18
Situation
Performance slows down over time
Server Runs out of memory
Resolution
Disable statistics gathering in Arango
On the Host Server edit the file: /etc/arangodb3/arangod.conf
Find the line # gather server statistics
change statistics = true
to statistics = false
Save the file and restart the DB, Mars, and the Agents
Cause
The Arango database used by GroupWise Messenger, has a memory leak associated with its internal statistics gathering function. GroupWise Messenger doesn't utilize that feature of the database so turning it off will not affect Messenger performance in any way. Arango will fix the problem in a future release.
