20.14.4.2 Linux - Messaging Server Patch 120230-08 IMAP, POP and HTTP Servers Not Starting Due to Over Sessions Per Process

After installing this patch, when you try to start Messaging Server, the IMAP, POP and HTTP servers do not start and may send the following example error logs:

http server - log:
[29/May/2006:17:44:37 +051800] usg197 httpd[6751]: General Critical: Not enough file 
descriptors to support 6000 sessions per process; Recommend ulimit -n 12851 or 87 
sessions per process.

pop server - log:
[29/May/2006:17:44:37 +051800] usg197 popd[6749]: General Critical: Not enough file 
descriptors to support 600 sessions per process; Recommend ulimit -n 2651 or 58 
sessions per process.

Once these values setting in /opt/sun/messaging/sbin/configutil then imap server 
failed to start

imap server - log: 
[29/May/2006:17:44:37 +051800] usg197 imapd[6747]: General Critical: Not enough 
file descriptors to support 4000 sessions per process; Recommend ulimit -n 12851 
or 58 sessions per process.

Set the appropriate number of file descriptors for all three server sessions. Additional file descriptors are available by adding a line similar to the following to /etc/sysctl.conf and using sysctl -p to reread that file:

fs.file-max = 65536

You must also add a line like the following to /etc/security/limits.conf:

*   soft  nofile  65536  
*   hard  nofile  65536
