Most importantly, what version of the JDK are you using? (and are you
running on an SMP system?) - there are some bizarre sigsev violations that
i've made disappear by upgrading to the latest JDK.
The other possible issue you're running into is linux typically has set
limits on the number of file descriptors (which network connections are
a type of) per process, and this number is typically around 1024...
(and given the other file descriptors that may be open internally for
other purposes - would explain your crashings around the upper 900's)
echo "Upping system limits"
echo 16384 > /proc/sys/fs/file-max
echo 65536 > /proc/sys/fs/inode-max
is what I use on our production servers. Note - you -may- have to
make a kernel change to go to some of these higher numbers...
