[Mailman-Users] Messages just began to be shunted, can't figure out why.

[Gary Goldberg]

Hello. I've had a long running Mailman installation with about a dozen lists
spread over four domain names on a Dell PowerEdge with 3GB RAM running CentOS
3.9 (fully patched). We're using the non-default Sendmail 8.14.1. I've upgraded
to 2.1.11 in June and everything was working fine/clean until last Friday
night.  We had a problem with our SpamAssassin subsystem dropping offline for a
few hours, and we rebooted the machine to reset everything.

Since then, messages I attempt to post to a Cub Scout list hosted in Mailman
have been shunted. Unshunting them just requeues them again. This is the error
message text I'm getting:

-----------------

The system doesn't appear to be out of memory, as suggested by another message
exchange here. The system has python 2.2.3 installed. Can anyone suggest a line
of attack for figuring this out and dealing with it? I reinstalled mailman over
top of the current installation -- no apparent difference.

Thanks in advance for any insight. -Gary
