Environment

Novell NetMail 3.5.2
Novell NetMail 3.5.2d
Novell NetWare 6.0 Support Pack 5

Situation

NetMail server is not responding
Cannot ping the server
Cannot send and receive
Utilization pegged but not necessary %100
ECB alloc fails climbing when looking under _tcp on the server Console
Cannot unload NetMail or takes a very long time to unload
NetMail insure audit logs filling up and taking a great deal of disk space, logs contain same errors over and over
ERROR:
NetMail\nmapd.nlm\Unhandled Request: Unhandled request "2100 Command unrecognized." for account "(null)" from 0.0.0.0
[15:08:07]
NetMail\nmapd.nlm\Queue: Processing queue 2 entry"83739577"
[14:07:39] NetMail\nmapd.nlm\Queue: Queue agent 1.0.0.0:14340 failed to process queue 16777343 entry

Resolution

This issue has been reported to development.
The current work around:
1. Delete the qclients file found in the novonyx\mail\DBF folder (You can also delete the whole DBF folder since when NetMail is restarted it will recreate this folder.)
2. Restart NetMail
NOTE: An automated work around to this issue would be to add a command in the autoexec.ncf to delete the above mentioned directories for you when the server restarts.
Steps to create automated commands in the autoexec.ncf
1) edit sys:\system\autoexec.ncf
2) add the following lines before the command that loads NetMail (IMS)
load toolbox.nlm (utility that when loaded will allow you to use the del command on a NetWare server)
del sys:\novonyx\mail\dbf\qclients (command that will automate the deletion of the needed directory)
ims (This line is already in the autoexec and is the line that loads Netmail)

Additional Information

Note: To check the Tcp allocation failures on the server console type _tcp then choose option number 1
