[Orca-users] SE Toolkit 3.4 - segmentation fault

	I was receiving segmentation faults on se 3.4  as well on solaris 10 with certain external SAN disks attached. It was happening when diskinfo.se was walking through the device tree.  I recompiled se on Solaris 10 and the problem went away.  

  Using the debug option on se:

short_name = sderr.name$<sd287,err>
strtok(short_name<sd287,err>, <,>)
if (short_name<sd287> == name<sd287>)
return sderr(STRUCTURE);
ld = readdir(dirp<18446744071530611328>)
if (count<32> == GLOBAL_diskinfo_size<266>)
dp = *((dirent_t *) ld<18446744071530634992>)

truss output

Subject: AW: [Orca-users] SE Toolkit 3.4 - segmentation fault

Hi David,

I am using the last snapshot Orca 0.28, but I´ve still the problem. Perhaps there is something special
with Solaris 10, Sun Cluster 3.1.....I did some traces (starting orcallator with truss, and I got some errors
concerning "kstat". Could there be a problem in orcallator.se???

What rev of orcallator.se are you using and what rev of Orca itself are 
you using?

If you're using Orca 0.27, you need to grab the latest snapshot instead.

If you're using orcallator.se 1.37 or earlier, you need to grab the 
latest snapshot, and extract the orcallator.se from it.

If you're using new stuff, but still seg faulting, that's a new problem, 
and we'll need more info (cut&paste some errors, for example).
