Dedicated application pools stop when accessing the websites

[iopsec]

Hi there,

I have an issue with Plesk 11. I have a few websites with different subscriptions, each running in a dedicated application pool.

The moment I access the website (via browser), the application pool is automagically stopped and 503 Service Unavailable is returned.

After I manually start the application pool, it runs (no stop icon for that app pool in IIIS Manager) until the first attempt to load the website is made.
The users for the respective pools are the ones created by Plesk when subscriptions were created.

Any idea why this is happening? Any help would be greatly appreciated! Thx


Details: Pesk Panel 11.0.9 Update #53, IIS8, running on Windows Server 2012.

Am I the only one experiencing this issue? No thoughts on this?

not enough info for decision. Pool can be stopped because of worker process crashing . Also you can search into:

Hi SvetlanaS,

I agree it was not enough information on my original post, but I managed to solve the issue.

The cause for application pool stopping on accessing the website was due to the lack of permissions. This was happening because my inetpub directory was moved from the default location of C:\inetpub to another drive. In the Parallels DiskSecurity.xml settings file, the permissions for Psaadm and Psacln are set with %SystemDrive%\inetpub directive which resulted in granting the permission to the old/default C:\inetpub. Changed that to my new path and reapplied the rules and it works now.

Thanks for replying though!

Thank you for quick reply.
Such issue with permission was fixed in Plesk 11.5 (scenario when inetpub location was changed by executing script moveiis7root.bat and only after that Plesk was installed.)
But you should remember that the only one correct way for changing virtual host location with pemissions is to launch "Plesk Reconfigurator".

OK, good to know, thanks.

you change the application pool settings from IIS, try resetting the recycle time and other session times. That should help you.
