We are running HP-UX B 11.23 on a rx7620 based systems. the core files generated on these boxes seem to truncate after a 2 Gig limit. Is there any kernel parameter or any setting which places this limit on the core files. The logical volumes on these machines can support Largefiles.
Thanks in advance for all your help.

# ulimit -HSc
what it is saying? If you want to have unlimited then,
# ulimit -HSc unlimited.

Limit at 2Gb seems more to be a filesystem limitation. Is largefiles option activated on this filesystem:
# fsadm -F vxfs /filesystem_path
if reply includes "nolargefiles", that's the reason.
You can allow largefiles using:
# fsadm -F vxfs -o largefiles /filesystem_path

Core files truncated at 2G limit

My understanding is the coredump (blocks) is set to 4194303 blocks, and block size being 512 bytes. This sets the limit to around 2G.
I have changed the ulimit to unlimited. Will try again.
Thanks for all your help.
