           Summary: mass-check --net doesn't run to completion (process
                    hangs)
           Product: Spamassassin
           Version: SVN Trunk (Latest Devel Version)
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Masses
        AssignedTo: spamassassin-dev@incubator.apache.org
        ReportedBy: cmt-spamassassin@someone.dhs.org


The mass-check program is hanging randomly when doing a mass-check --net.

- strace -p <pid> reveals the processes are waiting in recvfrom(<fd>, 
- <fd> is always a UDP socket
- The hanging seems sporadic at best, although I have yet to get fully through a
mass-check --net.  Sometimes it hangs after 1000 emails, sometimes after 7500.
- My corpus size is currently about 4000 ham/4000 spam.
- My primary DNS server is running on the same LAN as the mass-check box.
- Killing a hung mass-check process via (-HUP || -TERM || -KILL) results in a
defunct process.  The controlling mass-check script does not spawn a replacement.


I have yet to make it all the way through my corpus after about 10 tries.
