This is probably not the real issue. Which OS are you running on? I
suspect your are running out of file descriptor (ulimit -n). Is you
application opening socket/stream by any chance? There is either a leak
with your application, or the OS you are running on doesn't have enough
file descriptor available for the number of concurrent connections
GlassFish is servicing.
