I am getting the following error when I try to start the jboss server on UNIX box. I have tried by increasing the 'limit of number of open file descriptors to 1000000 by using the following command ulimit -n 1000000. But still the same problem persists. Please help me in figuring out the problem. Thanks in advance.
