[stunnel-users] accept : too many open files error(24)

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

Senthil
