Bugfixes:

1) Kernel deadlock on ext3 filesystem on high system load;
2) Quota inode statistics.

Recomendations:

1) In this version of FreeVPS kernel, it is not recommended to decrease Memory Limit without restarting VPS. Decreasing memory limits "on the fly" reduces new processes not being started. So you need to stop/suspend VPS, decrease Memory Limit, start VPS (resume if suspended);
2) It is recommended to turn off Memory Limit (set Memory Limit to 0) in VPS with high load. Then you will be able to run processes that require a lot of virtual memory (for example, Java processes);
