Hi,
I finally made some tests with mina-rc2 trying to reproduce the oom.
I didn't succeed to reproduce it when stressing james with normal mails
(well-formed,...).
I would tend to follow the pointer Norman gave about the infinite loop
in the exceptionCaught() method (writing on the session recause and
exception,...)
http://svn.apache.org/viewvc/james/server/trunk/smtpserver/src/main/java/org/apache/james/smtpserver/mina/SMTPIoHandler.java?revision=930014&view=markup
I think that some sockets behaving badly may be the cause and tried to
simulate this with long-time opened connection, with garbage being sent
on the sockets,... without success (no exception).
I will now roolback to the previous version of SMTPIoHandler with james
not closing the mina session, and see what I can find.
If you've got some idea of patterns, datas,... to send on the socket to
make mina throw an exception, just post it.
Tks,
Eric

Hi Ashish,
James in running with netty since 2 days.
I plan to let it run until this Friday (if no problem).
Thereafter, I will go back to mina.
The logs I've got are not helpfull and show nothing, except a sudden
java OOM.
I may try this weekend to find a reproducible way to have the oom.
Tks,
Eric

We need to let Eric test it again. Currently he run the netty version
of james to see if the cause is really MINA ..
Thx,

Hi Ashish,
I bet its the loop I mention before.. This would make sense when
looking at the growing queued writes. I commited a change to trunk
which close the session after write the data to the client. We will
see if this helps..
Thx,
Norman
