[Mailman-Users] Approved message is discarded

[Rosenbaum, Larry M.]

We are running Mailman v2.1.13 on Solaris 9 Sparc.  We have a list with about 13,000 members that we currently have "emergency moderation" turned on because of previous problems with reply storms.

Today somebody sent a message to the list, which (of course) was held for moderation.  The list owner approved it, but then it disappeared.  Here is what was in the "vette" log:

What caused the message to be discarded after it was approved?

Thanks,
