[rt-users] Issue with rt-mailgate

[Stuart J. Browne]

Hi,

I've got an RT 3.4.4 setup running (mysql 4.1.11-Debian_4sarge1-log/FastCGI 
2.4.2/Apache 2.0.54/Perl 5.8.4), and it was working well until a day or two 
ago.

For some reason, the messages stopped being inserted into the database 
reliably.

When trying rt-mailgate outside of the sendmail pipe, with --debug, I get 
this:
--------------------
# /opt/rt3/bin/rt-mailgate --queue support --action correspond --url 
http://example.com/ --debug < /tmp/mail.msg
Connecting to http://example.com//REST/1.0/NoAuth/mail-gateway at 
/opt/rt3/bin/rt-mailgate line 99, <> line 1.
An Error Occurred
=================

500 read timeout
This is /opt/rt3/bin/rt-mailgate exiting because of an undefined server 
error at /opt/rt3/bin/rt-mailgate line 147, <> line 1.
--------------------

This happens with all kinds of messages, both plain-text, and mime-encoded. 
It doesn't happen consistantly, as in sometimes it doesn't work, other times 
it does.

Sometimes this message gets inserted into the database, but it returns this, 
so is considered at failed delivery, so it is queued, and tried again later.

Thinking it might be due to concurrent attempts at running mailgate, I upped 
apache's max-clients, and also the 'FastCgiServer' -connections option, but 
it still occurs.

The database is in a good state (although I wouldn't mind pruning the 
Attachments table a bit (over a GB now)), and is responsive.

I'm not really sure where I should be looking next.

Any advice would be welcomed.
