Yes 14 is SIGALRM

Thanks Jan for your response.
I inserted this code in near the start, and in the global section, of my
mimedefang-filter, and got the error:
<snip>
Jan 18 22:27:48 hosta mimedefang-multiplexor[6491]: Slave 5 stderr: Argument
" at /usr/lib/perl5/site_perl/5.8.0/Mail/SpamAssassin/Loc..." isn't numeric
in alarm at /etc/mail/mimedefang-filter line 95.
</snip>

When I added an 'md_syslog('info',"alarm=$arg");' right after the
'CORE::alarm($arg);' statement, I got:

Any ideas what could be changed in your sample code to avoid this error?
