Recently, I've had a client who's had issues with uploading files and general functioning of the ISPConfig hosting control panel.
So the first thing I checked out was "/proc/user_beancounters", and everything seemed normal there.
Quick check with `vzquota` turned out that the inodes were maxed out.
Blocks and Inodes can also be checked/displayed within the container via `df -h` and `df -i`.
Additionally, since he had a lot of users, he was maxed out on the users limits too. Noticed that with `repquota -a` which pulled up a huge number of users.
Increasing the appropriate limits with vzctl on diskspace, diskinodes and quotaugidlimit resolved all issues.
