Try to find out what it's frozen on:  attach to it with gdb or a tracer and  
see what system call it's blocked in.  (I'd bet it's stuck writing to  
xmobar, which will have choked for some reason.)

Linux: strace
recent Mac OS X and Solaris: dtruss
older Solaris: truss
*BSD and older Mac OS X: ktrace
