Hello
when i execute a fortran binary, i obtain :

in workstation A:
./xstn001: 3594 Bus error(coredump)
In workstation B:
A good result.

My parameters in workstation A :
>>ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) 262144
stack(kbytes) 8192
memory(kbytes) unlimited
coredump(blocks) 4194303
nofiles(descriptors) 254

>>kmtune -lq maxssiz
Parameter: maxssiz
Current: 0x800000

Typical FORTRAN code requires a larger than default stack size. Use SAM to increase maxssiz and maxdsiz to match your "good" machine's value and then build a new kernel.
If this is a 64-bit version of HP-UX, you also need to make certain that the 64-bit cousin (e.g. maxssiz_64bit) are at least as large as their 32-bit counterparts. After making these changes and rebooting, run ulimit -a again to make sure the values match. It's possible that .profile (or /etc/profile) ulimit entries are also in effect.
