A master process running as root and a pool of workers running as clamuser would easily allow this (think Apache). It would allow existing processes to continue to completion and then die and new workers would start up with current configuration params. This could also include new user ID and path changes. The workers could also die off after handling so many requests so that memory leaks can be recovered. Lots of things can be done, in fact. Meanwhile, restart clamav if you change the config file :) dp _______________________________________________ Help us build a comprehensive ClamAV guide: visit http://wiki.clamav.net http://lurker.clamav.net/list/clamav-users.html
