memory alloc failed?

[Leon-32]

hi all:

     I have a multi-process project, it create and destroy 500 process per second, and maintain 3000 process, the beam use 900M memory to 1.2G, after running 20 hours, it was restarted by kernel, and i found error like this:

__alloc_pages: 0-order allocation failed (gfp=0x20/1)

   

    so, anyone can tell me some information or some tips? May I use garbage_collect() before every process exit to force free memory?

 

    great thanks
