needed a crash course in crash dump!!!!

[Jerry K. Lau]

My AT&T 3B2/600 crashed on Oct 10 and I suspected that the cause was the inode
table related.  Because the output of the "user" command showed
"inode of current directory: 599" and the tuneable parameter of 
ve_inode and  v_s5inode are set to 600.  Would anyone of you netters 
provide me with your expertise of what exactly caused my system to crash.

I would be grateful if you can send your response via email: 
	{pyrmaid!pacbell!pbhyf!jkl}

Thanx in advance.

J. Lau

P.S.
Below are the output from the crash dump.  If it isn't 
enough data for trouble-shooting, I will be happy to
send you more crash output.
