Node JS Process out of memory

Question

I am using forever JS to run my node JS server continuously, however occasionally the server crashes and site goes down for some time.

I looked at the forever logs, and here it shows:

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - process out of memory

Here are some more errors I found in my console.log file causing node to crash:

Any idea on how to fix this? I can't seem to find the error ?

You can try to increase the memory limit in node js using this,

node --max_old_space_size=8192 --optimize_for_size --max_executable_size=4096 --stack_size=4096

You can use it like this:

node --max_old_space_size=8192 --optimize_for_size --max_executable_size=4096 --stack_size=4096 yourfile.js
