you need to take a look at the memory image.

obviously, p is nil or garbage (you havnet told us the address
it faults on), but this should not happen. 

it is most likely that a memory corruption has broken the 
Proc* structures or at least the next pointer in one
of the proc's or the global _threadpq.

is there a way to reproduce it?

maybe you can make a memory snapshot if the process with
snap(4) when it happens again.
