Hi,
Thanks for prompt reply.
Here is file descriptor properties ... even manually i have increase
ulimit values of system before starting any services ...
[root@linux /root]# cat /proc/sys/fs/file-max
4096
[root@linux /root]# cat /proc/sys/fs/inode-max
8192
[root@linux /root]#
Btw i have change it to values you specified ... and tested
still same problem .......
For testing it is non SMP
Java is 1.2.2
Thanks again ...
Regards
Santosh Pasi
