You have memory overcommit turned off, thus it can't fork a new
process. You must find out what it taking up the virtual memory.

Note that in Linux, overcommit off limits the total virtual memory to
swap space + half of real RAM. How much RAM have you got and how much
active swap? If you have a server with lots of ram, you need at least
half that RAM as swap to be able to use it all...

Have a nice day,
