Hi,

I have some problems after this commit. The scenario is the
following:

I have a JBoss Application Server running on the FreeBSD 5.2-CURRENT
machine which connects to an Oracle database (on a Sun). On several
occasions the connection to the database is forcefully closed and I
see the following messages in /var/log/messages:

Jan  9 09:39:29 tybalt kernel: too many small tcp packets from
XX.XX.XX.XX:61701, av. 108byte/packet, dropping connection
Jan  9 09:39:35 tybalt kernel: too many small tcp packets from
XX.XX.XX.XX:61701, av. 108byte/packet, dropping connection
Jan  9 09:45:44 tybalt kernel: too many small tcp packets from
XX.XX.XX.XX:61701, av. 109byte/packet, dropping connection

Is there any w/around? What are the proper settings for
net.inet.tcp.minmss and net.inet.tcp.minmssoverload in my scenario?

Regards

        -Thorsten
