[Mailman-Users] mailman cron throwing persistent lock error (IOError: [Errno 2] No such file or directory...)

[Bob R]

Hi folks - I keep getting my mailman cron throwing and emailing me
consistent errors:


[somelist and myhost redacted...]


Example 1:

/usr/lib/mailman/cron/disabled

    main()
  File "/usr/lib/mailman/cron/disabled", line 150, in main
    mlist = MailList.MailList(listname)
  File "/var/lib/mailman/Mailman/MailList.py", line 128, in __init__
    self.Lock()
  File "/var/lib/mailman/Mailman/MailList.py", line 161, in Lock
    self.__lock.lock(timeout)

This seems to be the only list (of nearly 200) that throws this error.

The installation is running on an Ubuntu server per instructions here:

https://help.ubuntu.com/community/Mailman

I checked and fixed permissions:

sudo check_perms -f

I deleted and recreated the list:

sudo config_list -o somelist.cfg somelist;
sudo /usr/lib/mailman/bin/rmlist -a somelist;
sudo newlist somelist listmgr at mydomain.com mypasswd;
sudo config_list -i somelist.cfg somelist;

But the problem persists.  Any suggestions?
