What do you mean by "stop", do you mean the process was killed?
What OS are you using?  And how much RAM/swap space do you have?

If you are using Linux, maybe your process got killed by the
OOM Killer (Out Of Memory Killer) because sufficient memory
could not be allocated to the process because you are low in RAM/swap.
There is a message I believe in the syslog by the kernel when
this happens.  If you are using Linux and this is the case,
you might want to read the malloc manpages, right at the end.
