Solaris

hi everyone,

we have solaris 8 in sun v480 server.

it gives this error.

Segmentation Fault(coredump)

can anyone help me in this - urgently.

Regards

Karthik C

Try 'truss'ing the process - and see if that yields anything

Code:

truss -wall -rall -vall -f lpstat

Cheers,
ZB

can u explain what it will do

truss -wall -rall -vall -f lpstat

since because it is a production server and i am in client side

rgds
karthik C

man truss

Code:

 truss - trace system calls and signals

So this is safe to do. You'll need to be root though...

Cheers,
ZB

after running this truss -wall -rall -vall -f lpstat.

It runs 100000 lines i am unable to read that one.

can u help me in this

Could you save it to a file and post the last 50 lines or so?

Code:

truss -wall -rall -vall -f -o /path/to/outputfile lpstat
