We're using clamav (clamd, together with exim) in our setup. Our setup consisting of currently four servers assigned to this task is processing around one million deliveries per day, around 3.5 million rejects in the same period. There were times, when we also had problems with hanging clamd processes, but for several months this setup is quite stable now. We're using FreeBSD 6, amd64. Servers have 4 GB of RAM, we needed to tune a bit in the config files of clamd so that it's leveld fine with our load. Also we use it successfully with libthr instead of libpthred (through libmap.conf). At least for a recent 6-STABLE, recent clamav and the given configs I cannot agree with you on missing stability. - Oliver -- | Oliver Brandmueller | Offenbacher Str. 1 | Germany D-14197 Berlin | | Fon +49-172-3130856 | Fax +49-172-3145027 | WWW: http://the.addict.de/ | | Ich bin das Internet.
