httpd.worker processes starting with less "Max open files" on RHEL 6.1

Ashokraj

Hi  ,

I am seeing "Too many open files" error in our OHS log, max open file limit is set to 65535, but I am seeing the httpd.worker process starting with 1024 max open file limit

"opmn" daemon process is starting with 65535 limit, please check below output and let me know how to rectify this error.
