Error occurred during initialization of VM

Could not reserve e

Answer 1

I recently faced this issue. I have 3 java applications that start with 1024m or 1280m heap size. Java is looking at the available space in swap, and if there is not enough memory available, the jvm exits.

To resolve the issue, I had to end several programs that had a large amount of virtual memory allocated.

I was running on x86-64 linux with a 64-bit jvm.
