Bus Error(coredump)

Hi,
I am using HP-UX.
While i try to run the Sqlplus command using the shel script in encounter the following error:
<shell script name>[<line no>]: some number Bus Error(coredump)
What may be the reason behind this.
I read few previous threads in this forum where i found some similar case. There it was mentioned to use errpt. I used that but if was showing not found.
If anyone knows the problem then please let me know.
Regards,
Jayesh

All we really can say is that there must be a bug somewhere. See this post for some info on what a bus error is exactly.

What shell are you running?
