At present there are some patches, however any of them is not finished. I suggest to discuss in details a problem. The most important questions. 1. It is necessary to limit what resources? 2. How resources should be limited? Soft and hard limits. 3. How to count memory occupied with group of processes? 4. How to limit memory use? Whether correctly to kill processes? 5. How to limit use of processor time at absence in ULE separate turns of performance for jails? 6. Whether limits should be inherited at creation jails? etc. -- Menshikov Konstantin
