[Mailman-Users] Shunting due to unknown encoding?

[Nick Arnett]

The following is an error log entry that *seems* to be associated with
Mailman holding up delivery of messages.  If I do a bin/unshunt, that
seems to end the constipation for a while, although the same entries get
into the error log anew.

Any idea what can be done about this?  It appears to me that it's trying
to encode a string as unicode, but the unicode library doesn't recognize
"gb2312" as a valid encoding scheme...?  And so this particular message
is getting shunted, but should that have any effect on other messages?

Now that I look a bit further back in the error log, I find this:

> Sep 16 17:19:54 2003 (31186) Traceback (most recent call last):
>   File "/var/mailman/Mailman/Queue/Runner.py", line 105, in _oneloop

Error on the same, line, but different error.  Shortly thereafter, in
the smtp log:

> Sep 16 17:25:40 2003 (12262) All recipients refused: [Errno 4] Interrupted syste
> m call
> Sep 16 17:25:41 2003 (12262) All recipients refused: [Errno 104] Connection rese
> t by peer
> Sep 16 17:25:42 2003 (12262) All recipients refused: Server not connected

And then the floodgates opened and mail started going to the lists
again.  I think that at 17:19 I did a bin/mailmanctl restart, then at
17:25, I did the bin/unshunt.

Any help appreciated...
