Connection timing out *annoying*
Hi.
Currently performing a load test, 150 users, and I am getting the below
error, for 15 simulated users.
I have
maxThreads=3000
minSpareThreads=25
maxSpareThreads=400
acceptCount=10
connectionTimeout=-1
Xms=64m, Xmx=768m
Connection timed out from client (Grinder). As I have -1 connection
timeout, any1 have an idea why I get this message ?
Thanks,
Pete.

I have checked the amount of free file descriptors, and I never lose too
many. I start getting the socket exceptions before file descriptors even
get down to 200 free.
This should be my last hurdle to getting a decent load test before going
home to sleep so if any1 can help it would be appreciated !
Tx.
Pete.
Using netstat -a, I see loads of tcp connection in a "TIME_WAIT" state.
Accoring to man, this socket is "waiting after close to handle packets
still in the network", so does this mean I have some limitation in the
linux kernel or tomcat ?
