While I thought it was related to a dying disk used for backups, after
your post I think it might not.
Running 2.6.37 on openrd-client (ARM).
It started with hanging jobs on the backup disk. I stopped cron and
could kill most of the jobs. Some are still hanging though.
Since then (uptime 12 days) I see hanging procmail processes, and an
apt-get upgrade last week gave an unkillable dpkg process. All these have
nothing to do with the backup disk. CPU is maxed out:
