This bug report was submitted to the Debian BTS by Andrew Pam
<an...@sericyb.com.au> as bug #501964.  His initial report is quoted below.

For the last three weeks, every time the Xen VM is suspended for weekly
backups all spamd processes hang when the VM resumes, blocking all
incoming email until spamd is restarted.  The following appears in
mail.log:
