I have been seeing this on Solaris 10 . It seems that diskinfo.se gets a
value from readdir which is invalid and when dereferenced causes a
segmentation fault. Has anyone else seen this and have they found a fix
for it ? I have added the code detailed in the fragment below to stop
the faults and keep my systems monitored:

I have tucked this into include/diskinfo.se in the SE toolkit.

for (ld = readdir(dirp); ld > 0; ld = readdir(dirp)) {
      // grow the array if needed
      if (count == GLOBAL_diskinfo_size) {
        GLOBAL_diskinfo_size += 4;
        GLOBAL_disk_info = renew GLOBAL_disk_info[GLOBAL_diskinfo_size];

      // 09-12-2005 Carl Hack to stop segmentation faults - must be a
bug in readdir -
      if (ld > 18446744071543217903) {
     // get the segmentation fault here when ld is >

      dp = *((dirent_t *) ld);
