Resolution

Gwava's vs threads (scan threads) are configured in your MTA startup file (typically located in sys:\system on NetWare systems).  Your MTA startup file usually will be a variation of your domain name with a .MTA extension.  If you open this file with a text editor, you should see several switches at the bottom of the file that all begin with /vs.  These are your GWAVA startup switches.  In order to changes your threads, you'll want to changes the value of the /vsthread.  By default, your MTA startup file should look something like this at the bottom:

;========================== END OF FILE ===============================


/vsaction-DISCARD
/vstype-MESSAGE
/vsnamevalue-MTASieve
/vsthread-16
/vscan-EXCLUDE
/vsdomain-DUMMY

The default setting is 16 threads.  This setting will work fine for a majority of customers.  Changes to this value should be done in small increments.  If 16 threads isn't keeping up, then try 20 for a day.

After saving your changes, GWAVA and your MTA will need to be shut down and restarted.  Thread changes may or may not be noticeable right away.  Be patient.

Important:  vs threads should never be increased to more than 32, unless specifically directed to do so by GWAVA Technical Support
