503 errors in some Panel pages

radykal

New Pleskian
Hello, been using 11.0.9 until this morning.... just came back from holidays and noticed that some pages from Plesk Panel 11.0.9 (maybe last MU) were not working, the most important ones "reseller" and "tools", both are displaying 503 Service unavaible... so decided to upgrade to 11.5 and see if it would fix itself after all packets update but no... Im still getting 503 service unavaible when trying to access "Tools and config" and "Resellers" from the links on the left side menu.

Which logs should i start looking at to debug the issue?

Thanks you,

First of all check

/var/log/sw-cp-server/error_log
/usr/local/psa/admin/logs/panel.log
 
In sw-engine log file there are some:

[22-Jul-2013 17:15:12] WARNING: [pool sso] child 11072 said into stderr: "NOTICE: PHP message: PHP Warning: psasem_rinit(): failed to open semaphore file: /usr/local/psa/var/psasem.sem: Permission denied in Unknown on line 0"

And the date and time seems to be when im trying to access "resellers" or "tools".

In error_log:

2013/07/22 17:15:18 [error] 19223#0: *1000 FastCGI sent in stderr: "PHP message: PHP Warning: psasem_rinit(): failed to open semaphore file: /usr/local/psa/var/psasem.sem: Permission denied in Unknown on line 0" while reading response header from upstream, client: XX.XX.XX.XX, server: , request: "POST /relay HTTP/1.1", upstream: "fastcgi://127.0.0.1:19001", host: "XXXXXXX:8443", referrer: "https:/XXXXXXX:8443/sso/ui"

And in panel.log there is all these, but seems in the time it was upgrading from 11.0.9 to 11.5.x and the problem was there before the update:

User with requested name already exists

Woot!

Im using Google Chrome as default web browser and all the 503 errors are appearing only in Google Chrome. Just logged in with IE 10 to discard a browser problem and in Internet Explorer 10 seems to be all working OK, I can enter in Resellers and also in Tools without problems.... so is any kinda of javascript or client code that is not working as expected
 
I have the same 503 Error... Plesk Backup ist starting by itself. Again and Again and wont stop... At Backup the Website will set offline to 503... I have Plesk Version 11.5.30 #7.

Help will be welcome so my website is offline and online and offline and online... I dont find the error, why plesk start backup.

EDIT: There is a massiv Bug in Backup Manager. In /etc/cron.d calls "plesk-backup-manager-task".

There will be this settings in it: 5,20,35,50 * * * * root [ -x /usr/local/psa/admin/sbin/backupmng ] && /usr/local/psa/admin/sbin/backupmng >/dev/null 2>&1

I think there is a big bug in this file, 'cause backup start each 5,20,35,50 Minute. Thats bad, 'cause there are to many processes of it at last and my harddisk went full...
