I have a process that is eating up 6 GB of swap space.  At that point, =
FreeBSD 9.3 terminates a process.  However, occasionally its not the one =
eating up the space.  When I manually quit the process then the swap =
space returns to a few KB used.  The system runs fine after that.

I have very little knowledge of what this process is doing internally =
but would like to know what might be causing this issue.  There are 5 of =
these processes running (parent plus 4 children).  Normally each uses =
about 90 MB RES/SIZE.  However when the problem occurs they are about =
2GB RES/SIZE each.  The system has 4 GB memory.  I thought that a malloc =
would not be able to grab that much memory, even with swapping as it has =
to be in memory.  Could a malloc cause this growth in process size or =
need I look elsewhere?
