I have noticed a serious problem with the latest stable branch of clamav, at least on FreeBSD. There seems to be a large scale memory leak. Starting with 0.92, I have been running a 10 machine clamd cluster, 9 of which running FreeBSD 6.2 RELEASE and one running 7.0 RELEASE. With the exception of a couple of hiccups in the past, they have been running pretty flawlessly, serving about 30 mail machines running clamav-milter.
With the advent of the vulnerabilities in pre 0.95 releases, I upgraded to 0.95 a week ago. With the latest round of vulns., I upgraded to 0.95.1 yesterday. With both revisions, I'm seeing a constant escalation of memory usage to the point of killing the clamd process because it runs into the MAXDSIZ we have set of 1.5GBs of memory. Restarting the process just restarts the "fail counter" once again. In contrast, I never had any problems with 0.94.2, or the entire 0.94 branch for that matter. The memory usage for those versions would sit consistently between 100MB and 300MB of resident memory usage depending on load. I haven't seen anything from anyone else on the mailing list about this, so I'm not sure if this is something related specific to FreeBSD or, if it's the massive load we put on this cluster (these 10 machines together process approximately 65 million emails per day) that allows us to see this clearly, but it is quite clear to us. If there is any more info I can supply, I will do my best to do so.
