500 - Internal Server Error

[EnricoL]

I finished upgrading Plesk to version 9.2.2 without error notifications via email, but I am getting several errors:

Domains page: 500 - Internal Server Error / Service is not available now, probably your Plesk is misconfigured. No http or ftp services are working.

System usage is at 99,99%, I guess that errors depend on that.

If I restart VPS, suddenly system begins working again, but then the same errors are shown.

Any help would be really appreciated.

The best way to find out what is going on, is to check error_logs, try to see what is in there and you will find the solution.

Hello,

Make sure that Plesk 'httpsd' service is running in the container:

# ps -ax | grep httpsd

To see the detailed error report you need to enable the following options in /usr/local/psa/admin/conf/php.ini and restart Plesk panel:

display_errors = On
log_errors = On

Then log into Plesk not through VZCP but directly at http://server.tld:8880, go to the problem page and check for exact error reported by Plesk or check error messages in Plesk panel log file PRODUCT_ROOT_D/admin/logs/httpsd_error_log.

Please, see the following article for more information:

Hi,

It is also worth checking /var/log/sw-cp-server/error_log
In Parallels Plesk 9.x panel runs on lighthttpd server which logs errors to /var/log/sw-cp-server/error_log
And see /var/log/messages for general system errors.

Also check http://kb.odin.com/en/5977 - maybe this is your case.
