I set up a local test environment and eventually saw
(a) OutOfMemorys (but only after a longer period of time, with -Xmx64M)
(b) Not being able to terminate with control-c (seemed to be depending on whether Derby was instantiated or not, but can't confirm that)
(c) unexpected Postal terminations with many users (100.000)

But I am too new to this and would not say that i reproduced exactly what you saw. I have not been able to isolate problems to the DB-case.

I would like to go on testing especially with two things:
+ Switch between DB/file and see how these two compare
+ Be able to peek into Derby and see if there is really data written to the DB :-) (Maybe derby gives some more info on resource consumption)

A few questions turned up while testing:
How many users are you testing (local/external)?
How much heap should be given to James when load-testing?

Just out of curiosity: Why is DB not used for all repos?

We appear to have some major new problems with Derby support.  It fails in
entirely non-graceful ways, as shown by the attached.  Worse, we cannot kill
the process except with kill -9.

This was produced using the attached configuration file and:

 $ ./smtp-sink 192.168.1.6:2525 1 &
 $ ./postal -m 15 -p 20 -c 1 -r 100 192.168.1.101 userlist-postal - >
test.log &
 $ ./rabid -r 1 192.168.1.101 userlist-rabid -

The test runs for a few minutes, and then the problem surfaces.  So it
appears that I can spool, store and retrieve e-mail for a few minutes, and
them boom!

Does anyone spot anything wrong in my configuration?  Does anyone else have
time to be working on this?  :-)
