Plesk Unavailable / Service Down

M

Hello All,

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:

/etc/init.d/psa start

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.

EDIT:
To cover all the bases I have asked this question elsewhere, the response I received was "I'm going to put my money on the partition containing /var being full.". So pursuing that 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??)

Output from df -h is:

Filesystem Size Used Avail Use% Mounted on
/dev/md1 9.2G 5.2G 3.7G 59% /
/dev/md5 9.4G 2.2G 7.2G 23% /usr
/dev/md6 446G 5.2G 440G 2% /var
none 2.0G 8.0K 2.0G 1% /tmp

So if I am reading that correctly there is loads of space available

EDIT

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