Environment

Novell GroupWise 2014
Novell GroupWise 2012
Novell GroupWise 8

Situation

High Utilization issues on POA
Many clients or heavy IMAP traffic hitting the POA on a regular basis
Crashing POA linked to increased IMAP requests

Resolution

It is likely that the following switches will help IMAP performance with the POA:
--imapreadlimit, --imapreadnew, --udpslap

You can override settings provided in ConsoleOne by using startup switches in the POA startup file. The default location for the startup file varies by platform.
Linux: /opt/novell/groupwFull Screenise/agents/share/<nameofPOA.poa>
Windows: C:\Program Files\Novell\GroupWise Server\Agents

 
Add the following lines, wherever you see fit (location, in this case is not important):
--imapreadlimit <number> (See documentation - specifies limit in thousands allowed to download)
--imapreadnew (See documentation - downloads newest first rather than default oldest to new)
--udpslap (helps on POA with busy IMAP)
