lock/unlock controls disappears for certain domain

[Ray Lightning]

On one of my servers (Plesk 9.5.4, with all updates, debian 5, x64) happens something strange:

one of domains was automatically locked due to space limit (ok, normal, as expected), and no one (client-owner, corresponding reseller, me - admin) cannot unlock this domain, because link "unlock" disappears!!!

This problem exists ONLY for this domain!
I tried to change "status" field in psa DB for this domain to "0" (was "32"), and I tried to raise disk space limit, does not helps..

Screenshot attached... I'am confused...

That is something I have not experienced before, however as you dig or wait for some one with an appropriate answer, you can try switching on the domain name through your SHELL by running the command

/usr/local/psa/bin/domain --on domain.com
