RE: [hobbit] hobbitd_channel still crashing everyday

Ahh you are correct, my binary + source did not match

Here is the stack trace from the (correct) binary (it's still crashing)

All of them all show


program terminated by signal ABRT (Abort)
0xfee60717: __lwp_kill+0x0007:  jae      __lwp_kill+0x15        [

From this:

        /*
         * Try to fork a child to send in an alarm message.
         * If the fork fails, then just attempt to exec() the BB command
         */


Do you have any commands I can run in gdb or dbx to help further?

The name & inbuf are not defined when I try it with the correct binary  +
core

This trace doesn't make sense - the "bbh_item()" function isn't called from
the "load_hostnames()" function. So I think there's some corruption of the
stack involved.

Either that, or the binary you're running doesn't match the source code you
have (ie. your source files were not used to compile the binary that is
running).

If you load the binary and core into gdb as you did to get the stack trace,
could you then do this:
   gdb> fr 10
This should print out that you're now at stackframe #10, which is the
"load_hostnames" routine.
   gdb> p *inbuf
   gdb> p name
   gdb> p title
These print out the value of a number of variables.
   gdb> fr 9
   gdb> p *hostin
