Kernel Call Trace - Help Me Understand It


Hello There,


I am facing a strange problem with my written program. It goes to zombie state. When I give "echo t > /proc/sysrq-trigger", I get the following in "/var/log/messages" file.

----------some-code-----------
Apr 12 14:51:12 localhost kernel: Call Trace:
Apr 12 14:51:12 localhost kernel: [<021209d0>] do_exit+0x386/0x390

Apr 12 14:51:12 localhost kernel: [<0214e2d3>] sys_close+0x0/0x61

----------some-code-----------

Can some-one explain me the order of function call here ?
Did "do_exit" call "do_divide_error" OR vice-versa ?

Does "do_divide_error" function call says that my program some-where do "divide by zero operation" ?

Thanks and Regards,
Navneet Kataria
