Look like OpenVZ container. I play with this a lot.
First of all memory size, not always limits your need.
64M - to low. Hardly to run static serve apache. (moderate load).
VZ container also has limits for (sample from my server)

=============
Last columns show how many times, processes in vz were limited by
corresponding resource.
Since this my out server with my own container, I try to set maximum,
but even this high sometimes not enough.
So I am not recommend use business critical application in vz for this
reason. Or try to get more resources.

This often happens when process try to allocate memory with margin.
I had cases when something allocate 4G on machine with 1G ram.
And it works because, linux has ability to promise this allocation in
future.
In vz container this case would lead to killed or hang app.
