I want all processes that try to overuse memory to be killed and OpenVZ is supposed to do it.

Where did you get such information from?
|
openvz refuses resource allocation when the process requests a resource that is over limit. That's a fact, right?
a process that failed to allocate RAM will just die - that's common sense. I'm not really telling that there's an openvz feature that kills the process. Normal processes - mysql, apache, bash, common stuff - will die when they can't allocate memory, fork, etc. Maybe some custom badly written code won't, but commonly used software does.

But it cannot be an instantaneous process.
Is there a process that begins to consume a lot of CPU? What VE does it belong to?
|
Just a random common process belonging to the VE that has hit the kmemsize limit. It could be apache, mysql, named, bash, ssh - and it's not like a single process remains in top. All processes of this VE begin rotating in the node's top. This may sound shady, but please take into account that i only have several minutes to collect data before ssh dies.
