BIND problem
I'm seeing lots of:

in my log.
I looked on the web, and no suggestion helped. Except one: one of then said his worked when he ran bind (aka named) as root. I tried that and sure enough, it 'fixed' the problem. Until monit somehow noticed the DNS wasn't running and started it from /etc/init.d (I'm still running Wheezy).
It happens only on the master DNS server -- the slaves do their dumps successfully, or maybe they don't try.
I tried su -'ing from root to user bind (after giving bind a shell). No joy.
Everything in /var/cache/bind is owned by bind:bind, it's all owner and group writable, root manages to write the files, there are no complaints about the masters directory (there are also no files called tmp-*** in there), and I'm at a loss as to why there's a problem setting the modification time (touch does it just fine).
Has anyone seen this and fixed it?
I'm guessing somebody's just kidding about the directory they're trying to write into, and their real directory is owned by user nobody...
