MTA Shuts Down Unexpectedly
The MTA has been running smoothly, but stops unexpectedly.
If the MTA agent console is still displayed, exit it. If the
normal exit procedure does not work, use the system procedure for
terminating a program.
- If you are using the NetWare MTA,
use the NetWare unload command. If you have other MTAs running on
the same server, you should exit them before using the unload command.
The unload command unloads all MTAs running on the same server and
might not enable them to terminate gracefully.
- If you are using the Linux MTA, kill the first MTA
process. You might need to use kill -9.
- If you are using the Windows MTA, close the MTA
If the MTA shuts down again, exit it again, reboot the server,
then start the MTA again.
Occasionally, a badly damaged message file can cause the MTA
to shut down.
Check the contents of the MTA input queues in the domain and
post offices. For the locations of the MTA input queues, see
Transfer/Storage Directories in GroupWise
7 Troubleshooting 3: Message Flow and Directory Structure.
Move the message files out of the priority subdirectories
of each input queue, start the MTA, then copy the message files
back in groups, watching the MTA carefully to see if it shuts down
on a particular message file. If it does, delete the problem message
file so normal processing can resume.
Occasionally, a damaged domain database (wpdomain.db)
can cause the MTA to shut down.
Network connections are unstable.
Make sure the connections between the server where the MTA
is running and the servers where the domain database (wpdomain.db)
and post office database (wphost.db)
are located are stable. Repeatedly losing connections to servers
can cause damage to databases.
The MTA is encountering a problem with one specific aspect
of its functioning.
MTA startup switches are available to disable specific MTA
functions while allowing other functions to continue normally. For
example, the /noada switch disables the MTA admin thread.
If a specific MTA function is causing the MTA to shut down, you
might be able to disable that particular function with a startup

Transfer Agent in the GroupWise
7 Administration Guide.
Another program on the server is interfering with the operation
of the MTA.
If the MTA continues to be unstable, eliminate other programs
running on the server. If the MTA is stable when another specific
program is not running on the same server with it, a conflict might
exist between the two programs.
