Gentle People:

I have a question about "The Curious Mystery Of Killed Process At 4:56 AM"?
For some while now I have been developing a optimization application, which
depending on the machine may run for several days.

    The development process has played out over a month or more of
testing, finding many bugs
including several Segmentation Fault Crashes, which are usually found
and fixed
with the help of GDB.

    Now I have a new one: After running for several days the application
terminates,
and prints "Killed" in the shell window. Now know this did not likely
occur via the
keyboard because of physical security. Can a process kill itself? Is
this simply caused
by a bug which must be chased down? Could this be caused by a shortage
of resources?
Memory? Threads? Is there a limit on the number of threads?
I am running GCC 4.4.7 on CentOS 7.0

There should be more details in dmesg and log files.   OOM Killer is a
prime suspect.
