by most installations ulimit defaults to unlimited and only restricted by maxX_size* kernel params.

Post the output of ulimit -a

# ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 1048576
stack(kbytes) 8192
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 2048

Thanks

data(kbytes) 1048576
stack(kbytes) 8192
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 2048

so..

data is limited to kernel setting ( probably )
same with stack
coredump to 4M blocks ( @ 512 that is about 2G @ 1k blocks that is 4G )
nofiles limited to kernel setting.

now I assume you are looking to see how to increase your process dump size to something larger ?

Do you think that this describes it well?
(Oh, _your_ HP-UX system. I suppose that I
should know all about it.)

td176> ulimit -c
4194303
td176> ulimit -c unlimited
td176> ulimit -c
unlimited

td176> type ulimit
ulimit is a shell builtin.

So, things may depend on your shell, too, and
you haven't disclosed that, either.

"man sh"
"man "

td176> uname -a
