The memory mentioned there is virtual memory. Processes running on that server require more virtual memory than is available. The kernel then tries to release some memory by killing a process, but it doesn’t find any processes that can be killed. Therefore it panics.

Perhaps your application has a memory leak. Monitor its growth, and restart it when you see it gets too big. Or find out what causes the leak.

You could try to avoid the problem by allocating some swap space, or using a VPS with more RAM. If it’s a memory leak, the server will run longer but might eventually crash again.

You could also search the internet for the error message. You will get a number of results; pick the results that most closely resemble your situation.
