Novell GroupWise 7
Novell GroupWise 6.5
Novell GroupWise Internet Agent 6.5 (GWIA)
CheckPoint Firewall
SendMail server processing messages and sending to GWIA through CheckPoint Firewall
Very High Traffic on the GWIA


Messages stuck in the Receive Directory of GWIA.
GWIA is slow in processing messages.
GWIA threads seem to be maxed out.
Receive threads were set to 30.


Changed GWIA configuration to Optimize the speed:

a) Increased GWIA Receive threads to 254

b) Increased Inbound Conversion Threads to 15.

c) Decreased the Timeouts to 2 minutes for:
   1) Commands
   2) Data
   3) Connection Establishment
   4) Initial Greeting
   5) TCP Read
   6) Connection Termination
Check the server utilization.  If it is high, unload programs that are showing high utilization.  An example of this is unloading java with java -exit.

Additional Information

Packet Trace showed lot of connections being opened by SendMail. SendMail was closing the connection after 8 seconds of no-response from GWIA.
CheckPoint FireWall was closing the connection after 2 minutes.
Increasing GWIA threads place a demand on the server's resources. Too many threads can monopolize memory and CPU utilization.

Make sure you balance your processing speed requirements with the other applications running on the same server as the Internet Agent.

Increase Packet receive Buffers.

This option is available only for the NetWare version. If you leave the send and receive threads at their default settings, you probably will not need to change the Maximum Packet Received Buffers parameter. However, if you significantly increase the number of send and receive threads, you should increase the default Maximum Packet Received Buffers parameter to better accommodate the SMTP processes. You must change this parameter at the server.
