Openvz "Container already locked" Error Message Solution/Fix
I didn't find any useful information that actually fixed this. My VPS was in the "Running State" and I could not stop or restart it. I kept getting "Container already locked" no matter what Idid (I tried all the suggestions in the Google results for this error).
Most of the suggestions were for Windows but I only use Linux. The other solutioins also said to restart the VZ service or even the entire hostnode and this was not acceptable to me........
