Environment

Novell GroupWise 8
Novell GroupWise 7
Novell GroupWise 6.5

Situation

The GroupWise Internet Agent (GWIA)  server is in a high utilization state (100 percent CPU) and messages do not seem to be flowing and delivering.

Resolution

In most cases, when the GWIA is in a high utilization state, it is attempting to convert an outbound message from GroupWise proprietary format into a MIME or RFC822 format or it is attempting to convert an inbound message from MIME or RFC822 format into GroupWise proprietary format.

Procedure to determine problem message:

1.  Bring down the GWIA
2.  Move the following directory structures, they will be recreated automatically when the gateway is restarted.

<domain directory>\wpgate\<gwia directory>\wpcsout  (This is where the outbound messages will be located, specifically in the 4 directory below wpcsout)

<domain directory>\wpgate\<gwia directory>\receive (This is where the inbound messages will be located)

3.  Restart GWIA.  If the problem is message related, the gateway should not go to high utilization after being started.
4.  If the GWIA starts without issue, copy the files from the two directory structures that were moved into the new directory structures that were recreated in small batches.  If files encountered in these directories are extremely large, this could be a cause of the high utilization.  Usually these files are messages that contain multimedia files that should not be distributed through email.
5.  If the GWIA goes into a high utilization state while copying the messages, set the file aside and open a Service Request with Novell Technical Services. 

It would be a good idea to update to the latest Service Pack available for your version of GroupWise before opening a Service Request and try the message again after applying the update.  Problems with converting messages are often addressed in Service Packs.
