MAX file size limited to 2GB

Hi All,

We are running HP rp7400 box with hpux 11iv1.

Recently, we changed 3 kernel parameters

a) msgseg from 32560 to 32767
b) msgmnb from 65536 to 65535
c) msgssz from 128 to 256

Then we noticed that all application debug file size increase upto 2GB then it stops. So far we did not find any error in application despite debug file is incomplete.

Is the debug file size limited to 2GB size due to any of the 3 kernel parameters value change? If not, how to find out the problem?

Any suggestion will help us greatly.

Thanks in advance

Have you enabled the filesystem for large files?
ant:/home/vbe $ fsadm -F vxfs /sas_wks
vxfs fsadm: Cannot open /dev/esvg02/rlvol1: Permission denied
after a little su for you must be root for this...

ant:/home/vbe $ fsadm -F vxfs /sas_wks
largefiles

How to enable (if this is the issue...)
Use:
# fsadm -F vxfs -o largefiles /dev/vg??/rmylvol
or
# mount -F vxfs -o largefiles /dev/vg??/mylvol /mymount
Make sure that you make the necessary changes to /etc/fstab as well
/dev/vg??/mylvol /mymount vxfs rw,suid,largefiles,...inlog 0 2
