I think spamd will correctly reload configuration files with a HUP signal Oddly enough for some reason when I did a 'killall -HUP spamd' all the spamd processes were killed off rather than restarted! Secondly, the spamd man page mentions a warning about using HUP. It turns out that the problem is not with SA, or RDJ, as such, but with Fedora. To 'restart' SA, the fedora startup script issues a 'stop' then a 'start'. To help with this the 'stop' uses some script functions in /etc/init.d/functions. In particular it uses 'killproc'. That function tries to locate the pids of the spamd processes. It first looks for a pid file, /var/run/spamd.pid, but that doesn't exist. So it then calls the 'pidof' command. This returns a list of the pids. However, it seems that the child processes are listed first, so the last pid is the parent one. It seems that as the children are being killed off, the parent sees this and restarts a child! Hence the overall 'restart' fails. I have inserted 2 lines into 'killproc' to reverse the pid order. Now the parent pid is seen first and killed off first. Testing this, 'restart' now works fine every time. I'll submit this as a bug to Fedora Core to see what they say. Needless to say, this problem may be particular to Fedora, other unix/linuxes may handle restarts and/or pids differently, and so not see this problem. Many thanks for all the replies. Now we have sorted this 'bug' out, I'll see about automating RDJ :-) John. -- --- John Horne, University of Plymouth, UK Tel: +44 (0)1752 233914 E-mail: [EMAIL PROTECTED] Fax: +44 (0)1752 233839

RE: RDJ from cron - is it safe?
have there been problems doing this? RDJ will not restart the daemon or even keep changed rulesets if the lint returns an error. So, running it via a cron job is safe. It depends on how you're running SA. If you're using amavisd and you specify a restart script, make sure it restarts both amavisd and postfix. Otherwise the two can stop talking to each other, and your mail will get held up until you restart postfix and flush the queue. This may be unique to my configuration, but if so I'm not sure of the cause. -Aaron
