Hi All,

Could someone explain the meaning of the numbers after the ‘Run fault’
mean and how they should be used to determine a fault condition.

Thanks

293 is the pid
000b is the signal (11 = sigsegv)
000e is the kernel trap number (which maps to the intel signals…

most typical is 000e which is a page fault
0b trap is segment not present
0c trap is stack fault
0d trap is general protection fault
0e trap is page fault

the main one to worry about is the signal…

Also important – the lines come in pairs. The next line in the
traceinfo should be something like “last run fault at…” and give
the program name and some other useful stuff.
