>Description:

The machine simply crashed this afternoon. It dropped into the debugger:

panic: sbflush: cc 0 || mb 0xc1ff9300 | mbcount 0 at line 867 in file ../../../kern/uipc_socket2.c
Debugger("panic"), stoppped at Debugger +0x45: xchgl %ebx,in_Debugger,0

(I've not copied all those numbers because they were too many and I was in a hurry, sorry)

I'm going to update to lastest code and try but this will take
a while because the machine is too slow.

>How-To-Repeat:

It's never happened and I don't know how to reproduce.

>Fix:

I've no idea.

Responsible-Changed-Why:  
Panics in uipc are probably rwatson's fault.  :-) 

He probably fixed whatever problem this was a long time ago, but I'm 
assigning this to him and he can decide if he wants to close it.
