Fwd: Re: buildworld panics with yesterday's kernel ...

[Andrew Atrens <atrens@xxxxxxxxxxxxxxxxxx>]

Hi Matt,

I forgot to add ... the other symptom I see is that various shared libs,
/usr/local/lib/libggi.so.2 for example seem to be getting corrupted in
the vm cache.

At some point mplayer stops working, and when I try to re-run it I get
errors about libggi.so.2 being just 'data'.. In fact 'file' reports it as
 just data.

# file /usr/local/lib/libggi.so.2
/usr/local/lib/libggi.so.2: data


So I made a copy of the file

# cp /usr/local/lib/libggi.so.2 .

and compared them.

# cmp -l /usr/local/lib/libggi.so.2 libggi.so.2

the same.

I then rebooted, and compared them a second time -


$ cmp -l libggi.so.2 /usr/local/lib/libggi.so.2
     1   0 177
     2   0 105
     3   0 114
     4   0 106
     5   0   1
     6   0   1
     7   0   1
     8   0  11
    17   0   3
    19   0   3
. ..
  4069   0  22
  4071   0  10
  4073   0  20
  4074   0   7
  4085   0  20
  4089   0 155
  4090   0   6
  4093   0 245
  4094   0 205

so it looks like, in the vm cache, the first 4k of the file
was 0's....


Andrew.
