Stefano,
Sorry to bother you again on this. But I've determined that James is
actually not sending the final expected SMTP response. I did an ethereal
packet trace and initially determined what what happening. Then I traced
back through the JAMES logs and verified what I saw in ethereal.
I don't know if it's really a JAMES problem. However, I have determined
that JAMES is NOT sending the 'message received' response when I use the
mySQL huge config (the mail DOES get sent) When I change back to the tiny
config, JAMES does send the response. This is very reproducable.
In the failure scenario, it appears that the smtp thread gets the message
and forwards it to the spool, but then simply goes away (see comparison
traces below).
The database is running fine in 'huge' mode (actually significantly more
efficiently). So I can't see anything that would point to database failure.
I have all the logs set to "DEBUG", and haven't found anything relevant.
But to be honest, I'm not sure where to look or what I might be looking for.
Please take a look at the two traces below. I'm very willing to drill down
and do more debug. I just need some pointers as to where to look.
The bottom line is that I really need to get mySQL tuned in order to free up
CPU. But I'm stuck with a pegged CPU in order to send mail. I guess I
could start trying a bunch of tweaking of mySQL parms. But not knowing what
the real problem is, I would simply be shooting in the dark. And even if I
got to accidentally work, it'll probably start failing again at some
inconvenient time. So I'd really like to figure out what is happening. But
I'm going to need a bit of help from somebody that understands the details
of the code to give me some pointers.
Thanks a bunch.
