I didn't see any output from that debug statement at any time during the half dozen test messages it took me to trigger the crash (I verified that it did get compiled in). The traceback (modulo transcription errors) is as follows: _tcp_timers(f0784500,0) at _tcp_timers+0x124 _tcp_usrreq(f077c300,13,0,0) at _tcp_usrreq+0x3fd _tcp_slowtimo(0,f0123cf8,f01aafb8,f010bbe4,0) at _tcp_slowtimo+0x6b _pfslowtimo(0) at _pfslowtimo+0x23 _softclock(80000000,f0780010,10,0,f0784000) at _softclock+0x64 doreti_swi(0,f0181fe0,11111111,22222222,33333333) at doreti_swi+0xf _cpu_switch(11111111,22222222,33333333,44444444,55555555) at _cpu_switch Mark. -- "Tigers will do ANYTHING for a tuna fish sandwich."
