This sounds interesting.. but I am also guessing this is on Windows?
Usually before I run a load test I do these optimizations for the
underlying TCP stack - these are common stuff usually suggested for many
applications.
echo "1024 65535" > /proc/sys/net/ipv4/ip_local_port_range
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout
echo 2097152 > /proc/sys/fs/file-max
echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle
echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse
ulimit unlimited
Any possibility for you to try this on Unix if its already on Windows? I
load tested the nhttp transport using apache bench sometime back and I
fixed the issues I encountered. I do not think I did any major
modifications to the code from then onwards - however I will try it once
again to make sure. Is it possible for you to also turn on DEBUG logging
for the nhttp transport through the lib/log4j.properties file and if
possible share the jmeter script with me or tell me what it does?
thanks

I've been trying to use JMeter to test Synapse but getting
intermittent failures, see below for the stack trace output. Happens
all the time, maybe a few hundred requests are successful but then it
gets the failure and hangs. I'm not sure whats the easiest way to
debug this is, any ideas?
