[Mailman-Developers] Cron error messages

[bronto]

I've been getting some cron error messages, using v2.1b2 and then 
2.1b3.  I posted this recently in the regular mailman list, but got 
no help.  Maybe here?

Here's what I posted on September 23rd:

"I'm running Mailamn v2.1b2, and just got these errors sent to my email:

_________________________________________________________________________

They came five minutes apart.  The reference to "gate" suggests to me 
that it might have something to do with newsgroup syncing, but I'm 
not doing any of that.

Since posting that, I have discovered that one of my mailing lists 
has stopped functioning to some degree.  I had set up this particular 
list to be a simple personal archive of messages from another mailing 
list I subscribe to.  It doesn't send anything, so I hadn't noticed 
any problems.  While doing my mailman update to 2.1b3, I discovered 
that no messages have been archived since the 23rd when I got the 
above errors.  Snooping around the mailman directories, I see a ton 
of files (several hundred) in the qfiles/shunt directory, dated since 
9/23.  There are also a few dozen from 7/2, FWIW.  I'm betting this 
isn't a coincidence, but know nothing more than that.

Today at 12 noon, I received the following cron error:

_________________________________________
Traceback (most recent call last):
   File "/usr/local/mailman/cron/gate_news", line 44, in ?
     from Mailman import MailList
   File "/usr/local/mailman/Mailman/MailList.py", line 31, in ?
     import urllib
EOFError: EOF read where object expected
__________________________________________

Since that time, there has been a mailman process running taking up 
all available CPU cycles.  gtop shows that the CMD is 
/usr/bin/python2, FWIW.  There are a fair number of qrunner processes 
running, but my mailing lists are hardly active.

What's going on here?
