Question

I am trying to run java command in linux server it was running well but today when I tried to run java I got some error-

Error occurred during initialization of VM

Could not reserve enough space for object heap

Could not create the Java virtual machine.

my memory space is –

root@vps [~]# free -m
         total       used       free   
Mem:     8192        226        7965    
-/+ buf: 226         7965
Swap:    0           0          0

How can I solve this problem?

Answer 1

The machine did not have enough memory at that time to service the JVM’s request for memory to start the program. I expect that you have 8 Gb of memory in the machine and that you use a 64-bit JVM.

I would suggest you add some swap space to the system to let it handle spikes in memory usage, and then figure out where the spike came from.
