If a program hangs, it hangs because it is in a loop or it is blocking on an
RPC or other event. Both can be easily seen with gdb.

You can try rpctrace, although it is a bit buggy itself.

Using gdb is an excellent idea. You better become familiar with it today

(install libc0.3-dbg and run programs with LD_LIBRARY_PATH=/lib/debug, so
you get debugging symbols into libc).
