I'm not doing anything clever here, so I won't answer this bit. > 2) I've been monitoring the clamd process with top and it never seems > to take more than about 30Mb of total memory (physical + virtual), so > I'm curious why it would be choking with a softlimit of 50Mb. > Thoughts? The 30MB you see is the idle memory usage. When it is actually scanning something, it recursively mmap's it, so it can get quite large. This may be a bug, it may be a feature - my jury is undecided. But it does not surprise me that sometimes clamav needs more than 20 MB to deal with a multipart mime message. > 3) Are other mail admins out there seeing these huge file attachments > coming in?

What > do other clamd users have your max file size set to? I limit the message size limit in the MTA. I see no point in unduly stressing clamav when I have already guessed that this is junk mail I'm not interested in receiving (that's the royal I, at least for the domains I am the mail admin for). -- -------------------------------------------------------------------------- | Stephen Gran | Delta: We're Amtrak with wings. -- | | [EMAIL PROTECTED] | David Letterman | | http://www.lobefin.net/~steve | | --------------------------------------------------------------------------
