corruption in /var/run/utmp

[Mark <mark@bish.net>]

This is on a debian system first of all.

I have recently started having problems with 'top'.

I would run 'top' and it would error out.  I have 'strace'd it and here's
what is stuffed at the end:

read(5, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 56) =
read(5, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
read(5, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 56) =
read(5, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
read(5, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 56) =
read(5, ")w\0\0\200\1772<r\6\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
write(2, "bad data in /var/run/utmp", 25) = 25
write(1,"\33[H\33[J\33[H\33[1m", 13)  = 13
_exit(1)

I cleared out /var/run/utmp - reset the ownsership and permissions and
then login with ssh.  Running top right after that again results in the
above problems.  Anyone ever seen this before?
