We are developing a servlet that is running within Apache Tomcat
(6.0.15).  We are currently using the NIO connectors with SSL enabled.
We are simulating heavy loads using approximately 200 simultaneous


All of this is running within Windows Server 2003 SP2.


Over the course of the test we notice that the afd.sys driver is
consuming kernel memory at a rate of 900KB per hour until the kernel
memory is exhausted (approximately 285 MB) and the system hangs.


Has anyone had experience with this sort of problem with other web
servers?  This same scenario actually runs with no memory leaks on
Windows XP Pro and LINUX.


We have tried a number of tweaks on the connector, in the TCP/IP
registry, and the AFD registry settings.


Any help would be much appreciated!
