In an 11.3AA image, I get a crash one minute FOLLOWING the random telnet connection: Program received signal SIGBUS, Bus error. 0x105284 in timer_running () (cisco-68k-gdb) bt #0 0x105284 in timer_running () #1 0xe5618 in notify_state_change () #2 0x4640ce in xot_context_detach () #3 0x469bde in xot_timed_wakeup () #4 0x450bc8 in x25lib_task () For cs-x25: make a telnet connection to a router configured for x25 routing, and type quit BillW
