[Orca-users] Segmentation Fault

[Cockcroft, Adrian]

1)       the RAWDISK stuff is obsolete

 

2)       are you running the "stable release" or the development build492? 492 has fixes in it for some of these problems

 

3)       the problem below seems to be that its reading a directory and getting a bad directory entry that is crashing it when it dereferences the pointer. This is not the same as the common problem of running out of disk slots. You san see that the current index is 30, and the size is 540 in the debug output below.

Hi, hopefully perhaps anyone can help. 
In earlier threads You've discussed segmentation fault which have occurred when using orcallator.se on systems with SAN-connected systems & large number of disks. 

I've installed latest SE-Toolkit with orcallator 1.37 on a FSC P900 (and also FSCP250, same result) with Solaris 10 & connected SAN-storage (EMC) with a lot of disk devices which have been assigned to this machine. 

Everytime when starting orcallator I get a segmentation fault. 

I've tried to exclude USE_RAWDISK and also to increase MAX_RAWDISK, both with no results. 

Has anyone an idea? 

Could it be a problem with SEtoolkit? I've tried additionally zoom.se included in the SE package - same result, error when greping san disk details! 

Debug output orcallator.se: 

ld = readdir(dirp<18446744071543194240>) 
if (count<30> == GLOBAL_diskinfo_size<540>) 
dp = *((dirent_t *) ld<18446744071543217776>) 
if (dp.d_name<c8t1d39s1> == <.> || dp.d_name<c8t1d39s1> == <..>) 
if (!(dp.d_name<c8t1d39s1> =~ <s0$>)) 
ld = readdir(dirp<18446744071543194240>) 
if (count<30> == GLOBAL_diskinfo_size<540>) 
dp = *((dirent_t *) ld<18446744071543217808>)
