[Orca-users] Re: Segmentation Fault with 1.35

[J. Kyle Cummings III]

I discovered when I was testing this problem that one of the six Solaris 7
servers was corrupted.  I then got this from one that worked properly.

I was able to comment out the USE_RAWDISK statement and got it to work.

I have attached the disk information from the system which I got the trace
from.

Thanks!
