Strange error while working on RPC backend

[Derek Atkins]

My RPC Server "crashed" with this message (it didn't actually crash
per se, but the state is messed up enough that the next requedst will
cause a segfault.  I haven't yet caught one of these in gdb to track
it down).  Any ideas what this means or what might cause it?
