Hello all,

Never had this problem before; but this morning there was a crash as
the server was done with an rdump from another machine. Later it looked
as if it was going to happen again but with 'mt offl' i think i beat it
to crashing.

Here is some output:

Is there anything i can do other than cvsup until it's fixed?

Kind regards,

Frank Ederveen

p.s. I patched iostat.c a bit. It shows more drives, and still
     fits in 80 columns. ftp to news.via.nl and get it yourself
p.p.s i want to run 3.0, 'cause it has some nice new features >:-)
