Dear Johnathan,
My test client is located on a different machine and the ulimit
command gives me a response saying 'unlimited', Also in the ape.conf
file I have set the value of rlimit_nofile value to 99999, and I don't
get the socket error. To test the socket error we had tried keeping
the value of rlimit_nofile as 10000, and we did get it, but in the
above case I'm not getting any such error
Thanks,
Sudeep Sunthankar
