[Mailman-Users] Mailman can't post to lists users: checkdbs script outputs some errors, messages are enqueued in qfiles directory but never exit the queue.

[Umberto Modotti]

Mailman version: 2.0.7, installed from source distribution
OS version: Solaris SunOS 5.8 patch 108528-23
Sendmail version: 8.12.10 patched

Since 2004, February 1st, at 05:07, mailman suddenly stopped to run.

I have just seen FAQ lists, and checked things as reported in section  
3.14 (Troubleshooting: no mail going out to lists members).

1) Here are the errors reported after launching the script 'checkdbs'  
by hand
------------------------------------------------------------------------ 
-----
Traceback (most recent call last):
   File "/local/home/mailman/cron/checkdbs", line 92, in ?
     main()
   File "/local/home/mailman/cron/checkdbs", line 43, in main
     count = mlist.NumRequestsPending()
   File "/local/home/mailman/Mailman/ListAdmin.py", line 96, in  
NumRequestsPending
     self.__opendb()
   File "/local/home/mailman/Mailman/ListAdmin.py", line 69, in __opendb
     self.__db = marshal.load(fp)
EOFError: EOF read where object expected

2) Here are the errors reported in ~mailman/logs/error trying to post a  
message

3) Messages are enqueued in qfiles directory but never exit the queue
4) No other errors in log directories.

Thank you for your help.
