[Mailman-Users] (no subject)

[Mark Symonds]

Hello, 

Had mailman working wonderfully here until three days ago, 
when a larger list (just over 2500 users) ceased functioning 
and I noticed the load average was through the roof (usually 
it's very low): 

[root at tx exim]# w
  1:24pm  up 387 days,  2:26,  1 user,  load average: 4.21, 4.29, 4.24
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU  WHAT
mark     pts/0    ca1.symonds.net   1:19pm  0.00s  0.28s  0.01s  w
[root at tx exim]# ps auxw |grep python

[root at tx exim]#

...read FAQ 4.19, killed the qrunner processes and removed the 
lockfiles.  Still no joy: 

[root at tx Mailman]# w
  4:44am  up 387 days, 17:46,  1 user,  load average: 1.08, 1.07, 1.26
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU  WHAT
mark     pts/1    ca1.symonds.net   4:37am  0.00s  0.24s  0.02s  w
[root at tx Mailman]# ps auxw |grep python
root     11804 96.9 11.3 59256 57492 ?       R    03:59  43:54 python ./qrunner

In the logs:

[root at tx mailman]# tail qrunner

[...ad infinitum...]

Also during this time: 

* Trying to subscribe via the mailing list web page, upon 
  clicking the "subscribe" button it hangs at the page 
  until the browser times out. 

* Same thing when trying to auth via the admin web page. 

* This is the only broken list on that machine.  The rest
  are functioning normally in all respects. 

* I thought perhaps someone had changed the domain preferences
  for the list?  Checked it with config_list and it is correct.  
  Also ran check_db and check_perms, both report all's OK. 

Exim 4, RedHat 7.0, Mailman 2.0.13.  

Ideas?

Sincerely,
