Hi All,
In UNIX, when all the process will be killed?  (Background is that
my app is dying with message as "killed" but there are no other users
on the system)?
I know of only two reasons, 1) explicitly send SIGKILL to app and 2)
other is when the CPU usage of the process reaches 100%.  Any other
reasons?

Regards,
Seenu.

(Sorry for type, it is not "when all the process" but "what are all the
reason when a process gets killed").

I know of no OS that kills process when it reaches 100% CPU usage.
OTOH, there are OSes that will kill process that consumed "too
much" memory.

Infinite recursion and other forms of stack exhaustion, and cases
where "normal" signal could not be delievered (e.g. because
sig{alt}stack established inaccessible signal-handling stack area).

In order to understand recursion you must first understand recursion.

It cud get killed , if the memory is restricted and paging space full .
Also lookout for the maximum number of processes allowed on the server
for that particular user.

I am saying this related to the OS AIX
