Strangely enough I have been looking at why SA has suddenly started to act
up and I also seem to be having DNS timeout issues after years of faultless
operation. I am running a local caching nameserver, but spamassassin -D just
stops dead as follows:

[8808] dbg: logger: adding facilities: all
[8808] dbg: logger: logging level is DBG
[8808] dbg: generic: SpamAssassin version 3.2.1
[8808] dbg: config: score set 0 chosen.
[8808] dbg: util: running in taint mode? yes
[8808] dbg: util: taint mode: deleting unsafe environment variables,
resetting PATH
[8808] dbg: util: PATH included '/usr/kerberos/sbin', keeping
[8808] dbg: util: PATH included '/usr/kerberos/bin', keeping
[8808] dbg: util: PATH included '/usr/local/sbin', keeping
[8808] dbg: util: PATH included '/usr/local/bin', keeping
[8808] dbg: util: PATH included '/sbin', keeping
[8808] dbg: util: PATH included '/bin', keeping
[8808] dbg: util: PATH included '/usr/sbin', keeping
[8808] dbg: util: PATH included '/usr/bin', keeping
[8808] dbg: util: PATH included '/usr/X11R6/bin', keeping
[8808] dbg: util: PATH included '/root/bin', which doesn't exist, dropping
[8808] dbg: util: final PATH set to:
/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/b
in:/usr/sbin:/usr/bin:/usr/X11R6/bin
[8808] dbg: dns: no ipv6
[8808] dbg: dns: is Net:NS::Resolver available? yes
[8808] dbg: dns: Net:NS version: 0.48

I have checked the version of Net:NS installed and according to cpan I am
up to date with version 0.6 so is there any relevance in the fact that the
above output says it's using 0.48?

That's it - I don't know if it's related to the OP's problem but any advice
is welcomed.

Thanks
