similar to: is this mbuf problem real?

In http://docs.freebsd.org/cgi/mid.cgi?200402260743.IAA18903 it seems RELENG_4 is vulnerable. Is there any work around to a system that has to have ports open ?

Hi all, I think I'm experiencing a bad mbuf leak or something of the sort and I don't know how to diagnose this further. I have a machine at home that is mostly used for transcoding video for viewing on my TV via the multimedia/plexmediaserver port. This software runs in a jail and gets the actual files from my NAS via NFSv4. It's a pretty simple setup and sits idle unless I am

Hi All, Mysql service is going down continously in my system due to lack of memory space. I checked the messages log and found the following error message.

Ive been googling quite a bit now for problems with running out of mbuf clusters. Im basically sending a 30k datachunk down 1000-4000 connections, but 1000 is more than enough to quickly fill upp 8192 mbuf clusters. I also tried setting maximum amount of mbuf clusters to 65536, but that only made the box hard-wire 86MB of 96MB RAM, making it just as unsuable as a dead machine. Of course, when the

Good day. Spotted the CVE-2007-1870: the clamav 0.90.2 is already in the ports, but no sign of the issue in the VuXML. The entry is attached. One thing that is a bit strange is that the ChangeLog for the ClamAV (http://svn.clamav.net/svn/clamav-devel/trunk/ChangeLog) says about CVE-2007-1997 as the libclamav/cab.c log entry, but I think they are messed the numbers -- there is no such CVE, at

yes unless you use the version as of :> 2004-03-02 17:24:46 UTC (RELENG_5_2, 5.2.1-RELEASE-p1) check it out with uname -a if it does not say -p1 it affects you.
