dispatcher Queue is backed up

NM: /mail/dispatcher/in Queue is backed up, 37 [GMS:SIAU:DISPATCHER]

The /mail/bin/gdservice processes the /mail/dispatcher/in queue. Sometimes a malformed mail on top of the list will cause this queue to back up. You need to remove the offending mail and run /mail/bin/gdservice from the /mail/dispatcher/ directory until the queue clears up.

After the procedure you may need to open a ticket with R&D and Tier II to have the offending mail together with the core file analyzed.

Detailed step by step example:

1. Log to the said node and do a long listing of the said directory.

<siau_root> cd /mail/dispatcher/in 
<siau_root> ls -l 
total 270 
-r--r-----   1 root     phoenix     5107 Apr  6 18:33 020406183352

-r--r-----   1 root     phoenix     2486 Apr  6 18:34 020406183403

2. grep for gdservice and make sure it is not running.
3. cd /mail/dispatcher and run /mail/bin/gdservice from this directory.

<siau_root>  
<siau_root> ps -ef | grep gds 
    root  9414   650  0 04:23:24 console  0:00 grep gds 
<siau_root> pwd 
/mail/dispatcher/in 
<siau_root> cd .. 
<siau_root> /mail/bin/gdservice 

4. If after running gdservice you encounter a core dump, move the first file you see from the long listing.

Segmentation Fault - core dumped 
<siau_root> cd in 
<siau_root> mv 020406183352 .. 
<siau_root> cd ..               

5. Go back to step 2 until gdservice is run successfully without a core dump.

<siau_root> pwd 
/mail/dispatcher 
<siau_root> /mail/bin/gdservice 
<siau_root> ls -l

6. Check the mail that was causing the core dumps and if it is unusual, have Tier II or R&D look into it.
