It would seem that when I attempt to access my Plesk admin page this is unavailable. After doing some cursory checks I discovered that the server was not listening for incoming requests on port 8443 (verified remotely via telnet).
I therefore assumed that the service was not running and therefore issued the following command via SSH under the root account:
This results in the following output:
Starting xinetd service... done Starting named service... done Starting mysqld service... done Starting postgresql service... done Starting psa-spamassassin service... done Plesk: Starting Mail Server... already started Starting Plesk... failed Starting drwebd service... not installed
As a possibly related issue, today I experience a server outage for reasons yet unknown. As part of the investigation into this I used Plesk to reboot the server. This action completed successfully and was the last action I performed in Plesk. Since the reboot I can access all services other than plesk itself.
Having never encountered this issue before, and also being something of a newbie when it comes to administering a Linux based server, I have no idea where to go next? Is there are log file I can check for service start errors? Is the solution staring me in the face? Or maybe something else.
Thanks in advance
EDIT Something else that may or may not be relevant:
After rebooting, and before attempting to access Plesk again I installed sysstat with yum in order to be able to use iostat. Other than that no other changes have been made to the server.
The last entry in the
/var/log/sw-cp-server/error_log file is
2010-12-10 18:35:34: (log.c.75) server started 2010-12-10 18:35:34: (network.c.336) SSL: error:00000000:lib(0):func(0):reason(0)
If I attempt to start Plesk with the command I mentioned earlier 2 new entries, the same as the one above, are added to the error log. I have found some reference to this error log entry and these relate to an updated version of SSL breaking plesk, however I have not (to my knowledge) updated SSL (unless the install of sysstat did this in the background??)
df -h is:

As the errors in the log seem to point to the issue that whose resolution is detailed here:
