+Sometimes using [[GDB]] on a system server can result in a [[deadlock]]. You
+can however still use GDB by using the [`set
+noninvasive`](http://sourceware.org/gdb/current/onlinedocs/gdb_19.html#Hurd%20Native)
+option. This indicates to GDB to not stop the program but allows you to
+nevertheless examine its state. Thus, you can get back traces and value of
+variables (and watch them change underneath you).
