I have a process setuid to root. It is controlling a SCSI device.
Sometimes the process get hung (still have not figured out why
and what sequence of the events cause this) and does not respond
at all even for kill -9. I am sending the kill signal as a root.
I have put some timeouts in the programs when it is reading data
but the progrm is not responding to any signals. What causes this
and how can i recover from this? I am running under SOlaris2.5
