Hi all,

I have been having an ongoing battle with Eventum and
bandwidth usage.

A couple weeks ago, I was seeing massive amounts of traffic
being  
sent from our server (7+ GB/day!) This is for a small (~200
visitors/ 
day) website, so I knew something was not right.

I eventually narrowed it down to Eventum - as best I can
tell, it was  
trying to send out e-mails, the e-mails were bouncing back,
creating  
more e-mails to send, and not having any success... they
just kept  
bouncing around in the system, building and building until
they were  
generating about 7G of traffic!

I went through the database, cleaned out these error
e-mails,  
installed a version of Eventum with the patch that Brian
sent around  
a couple weeks ago, and everything went back to normal.

Except now, I'm starting to see my traffic go up again.
I'm at 800MB  
today, up from 300 yesterday, up from 200 the day before.  I
removed  
Eventum from its directory and put it in a 'quarantine'
directory,  
and now my traffic has returned to normal. (~50MB/day)  Only
this  
time, I've looked through the database and I can't find
any errors or  
queued messages, no messages in the error logs, nothing.

The only thing I can think of is that sometimes people reply
to an  
issue that aren't on the 'notification' list, so their
message is  
'blocked' and made into a note.  Before, this used to
generate a new  
note every time the mail queue cron job ran.  Prior to the
new  
version, I would get an e-mail every time this happened, so
I would  
go in and add the person to the notification list, making
their  
message unblocked.  Now, the system just creates one note so
I don't  
bother adding them to the notification list.  Is it possible
that  
it's still creating all those notes and e-mailing it out
every time  
the mail_queue is processed, I'm just not seeing it?

Again, no error messages in the database, no error messages
in the  
logs, and nothing showing in the mail queue.  I'm stumped.

I'm using a nightly build (because it contained the patch),
but I was  
having this issue before with 1.7.1 Release.  It's on a
LAMP host.   
If you need any more detail, I'd be happy to oblige.

Any clues? Thoughts?

Cheers,
Andrew
