Plesk 11 Error 503 on Ubuntu 12.04

webhod

New Pleskian
Hi all,

from time to time I´m getting a 503 error message (Service not available) when accessing the panel site (https://hostname:8443). All other hosted homepages are working without any issues. It seems that just the panel crashes. I couldn´t find anything in the logs (/usr/local/psa/admin/logs/panel.log, /var/log/sw-cp-server/error_log) related to this. Nginx and Apache logs are clean as well...

I noticed that message when I´m accessing the Panel login site and Plesk redirects to "relay" (https://hostname:8443/relay => then to https://hostname:8443/sso/ui). It stops on the "relay" page with mentioned error message. Maybe this will help you to find the error.

When I restarted Plesk using /etc/init.d/psa restart anything works fine... Until the next crash in a few days...

I already read the kb regarding to this issue on windows servers but I could not find anything for linux systems...

OS is Ubuntu 12.04, Plesk runs on a dedicated server, not inside a VZ Container.

Any ideas?
Thanks in advance!

Chris
