HTTPS:8181 Not working

I have SJSAS EE 9 installed on RHEL 4. after installation i have migrated all web-apps from tomcat to SJSAS. HTTP port is 45925 and HTTPS 8181. how ever all the apps run fine on both ports for 24 hours. After that apps are running only on 45925. I am unable to open apps on HTTPS port.

i checked the server.log file....I found java.io.IOException ... Too many files open.

and automatic redeployment is not working... Kindly help...IS it a SSL problem. It happend with my TOMCAT server on same machine. https on 8443 stopped running with java heap size error. i set java heap to Xms512m Xmx512m. Thats why i migrated to SJSAS 9. The same problem persists.
