Operating With VPS Memory And Disk Limits
(version 1.2)

Memory and Context RSS Limits

• limit values depend on the number of VPSs running on the host, and tasks running on them;
• when summary virtual memory size used by VPS/context exceedes Memory Limit value, processes can't allocate the required memory and fail to run;
• if Memory Limit you set to VPS equals the whole virtual memory available on the host, in a while virtual server will use up all the host's swap;
• if you turn off both Memory and Context RSS limits, kernel can DoS or panic;
• it is recommended to set Context RSS Limit to one third of Memory Limit.

Disk Limit

While setting initial Disk Limit before VPS creation, please mind that it must be greater than the base Linux RedHat installation size (~450-500Mb). Otherwise, Disk Limit will be turned off during the installation.
