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 |
