Are you running 32-kernel for centos?
32-bit limits in the 4500 range for open connections due to the memory constraints
We usually set our open file limits to 100I specifically for Stunnel user

Hi
We are using stunnel 4.32 on centos and our ulimits in limits.conf are as follows
* soft nofile 16384
* hard nofile 65536
We keep getting the error “too many open files(24)” and stunnel does not accept new connection till we restart the same
Is this ulimit proper or we need to increase the same , we are look for 3000 to 5000 connections
Regards
