Hello,
A few minutes ago, I was filling up a PR for truss hanging the system, but my
data was lost right after I tried to save it. In fact, I lost many files
from my last "session", including the errors truss reported. As this is not
a test box, I won't do that again and I ask if someone has a 6.1 or 6.2 test
box to test it.
fsck complained:
Trying to mount root from ufs:/dev/ad1s3a
WARNING: / was not properly dismounted
Loading configuration files.
Entropy harvesting: interrupts ethernet point_to_point kickstart.
swapon: adding /dev/ad1s3b as swap device

WARNING: /home was not properly dismounted
/home: mount pending error: blocks 764 files 6
WARNING: /tmp was not properly dismounted
/tmp: mount pending error: blocks 0 files 1
What I did:
% truss -a cat <some_symbolic_link>
Repeat that lots of times. I was trying to gather the error messages
appearing at random (I remember "no such file or directory" for
/proc/<pid>/mem files, and another regarding "bad process" or something like
that). In my last count, I got 6 errors for 33 launches.
I'll try to update my -CURRENT testbox, but it will take lots of time (it's a
300 MHz Pentium).
What happened:
My box lost all terminals. None worked at all, and I couldn't open more
xterms. Some X apps continued to work, others started to fail. xmms lost
all of its configurations, Firefox lost some. I suspect that it's due to the
complains showed above (fsck).
There was no dump (or break to gdb), but soft-reboot didn't worked (CA-del),
so I pressed the reset button. Any other information I can provide?
