From nessus-update-plugins:
# HUP nessusd
test -f ${prefix}/var/nessus/nessusd.pid && {
pid=`cat ${prefix}/var/nessus/nessusd.pid`
kill -1 $pid 2>/dev/null
I've very rarely had to kill nessusd and restart it after a plugins update.
Kind Rgds,
Paul Rochford

Subject: Re: Updating Plugins During A Scan
Hi,
I am sure just sending Nessus a HUP is not quite enough for updating the
plugins. I've updated the plugins, done a HUP, and had weird
inconsistencies (and I'm not scanning; nessusd had no child processes).
If I then fully stop and restart it's ok. This has happened repeatably
with 2.0.7 (a little old I know).
Regards,
Paul
