Unfortunately, it doesn't seem as if the daemon is dying -- it just hangs. If it died then I could respawn a fresh daemon and everything would be fine. Instead, the daemon allows requests but then just hangs. > > segfaulted and clamd just hung.

Thanks. It has nothing to do with a virus. I attached a sample message to my original post, along with all of the debugging output fromthe library. It looks like the problem is a result of an "assert" statement when trying to parse an e-mail. When an "assert" fails, what is the library supposed to do? Is the failure supposed to be caught? --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
