After having used Spamassassin with mime-defang for some considerable time, with no problems, we are suddenly experiencing serious performance problems.
Last thursday, after effectively being mail bombed, which caused max mimedefang children to be spawned, and mail coming in at such a rate that the box basically couldn't handle it. Whilst trying to debug, we found we had an old (and potentially vulnerable) version of clamav installed. We decided to upgrade all CSW software, and did a "pkg-get upgrade". Having solved the mail overload itself, we now find that mimedefang children are spawned, but take so long to return that the machine is basically dead, and all mail is backed off with "please try later", forcing us to disable mime-defang/spamassassin. mimedefang/clamav runs just fine... Only clue I have is that if I run sa-learn, it takes minutes to respond at all, and in the output appears "Parsing of undecoded UTF-8 will give garbage when decoding entities at [...]/Mail/SpamAssassin/HTML.pm line 182" - although I suspect this message is a red herring... OS: Solaris9 spamassassin: 3.0.4 Sendmail: 8.13.4 clamav: 0.87 mimedefang: 2.52 perl: 5.8.7 I am getting desperate, so any help very much appreciated! john
