are you using m4 or m5? m4 had an issue with mySQL page size. but should be corrected in m5

you could try turning off compression, and see if you still get an error, but might not be suitable to your environment...I turn compression off on my server

may not help, but will be intersting to see if the issue still occurs with and without compression!

oooh,

in the jboss-service.xml, theres is an area which speaks of DOS attacks, and ammount of time to keep a socket open, maybe thats your issue, you might try it...it's here

<!-- defines an SMTP server. -->
 <mbean code="org.jboss.mail.Server"
 name="jboss.mail:type=MailServices,name=SMTP">
 <depends>jboss.mail:type=MailServices,name=SMTPProtocol</depends>
 <!-- protocol should reference SMTP -->
 <attribute name="Protocol">jboss.mail:type=MailServices,name=SMTPProtocol</attribute>
 <!-- port to listen on -->
 <attribute name="Port">25</attribute>
 <!-- which addresses to listen on 0.0.0.0 = all or localhost means only the localhost -->
 <attribute name="Address">192.168.69.1</attribute>
 <!-- timeout between commands (not presently supported) -->
 <!-- note from mikea: rfc 821 sets strict guidelines on allowable timeouts -->
 <attribute name="Timeout">30000</attribute>
 <!-- timeout for the connection regardless of whether it is finished. Thus it will kill the
 socket and thread mid-stream/operation. This should be big enough to allow whatever the
 messages you're sending while defending against folks who might try to DoS your server
 by keeping a large number of connections alive -->
 <!-- note from mikea: 10 mb in 120 seconds is about 100 kb/s - which may or may not be
 the actual bandwidth achieved depending on server. therefore, i believe this value should
 be set somewhat higher to avoid timing out on 10mb emails,
 and other methods be used to detect DoS's -->
 <attribute name="Life">120000</attribute>
 <attribute name="PoolSize">5</attribute>
 </mbean>

nice, very nice!

And congrats on getting code to compile. Wonder what the exact diff is, as we are staying with m4 for now.

"Head" works fine with me also! LOL, sorry...
