OES2SP2 i586

Installed/Configured OES2SP2 + iManager + iFolder + LUM on the same box for a POC at a customer end.

till yesterday iManager/iFolder was working fine, but now we cant access the following

https://ip.of.my.server/nps/imanager.html
and
https://ip.of.my.server/admin

i.e we got
Unable to connect
Firefox can't establish a connection to the server at ip.of.oes2.server.
the only page we can access is http://ip.of.oes2.server and Apache Tomcat page at http://ip.of.oes2.server:8080/

I think there must be something wrong with tomcat, because whenever I try stop tomcat, it takes 2 Minutes 10-17 Seconds, and during that time I continuously got the following messages at an interval of 2 seconds.

Nov 29 03:30:58 node1 su: PAM_NAM: pam_sm_acct_mgmt: pam_sm_acct_mgmt called without prior authentication for user [wwwrun]
Nov 29 03:30:58 node1 su: (to wwwrun) root on none

likewise tomcat starts very quickly, but then I also got the same message
