Some type of meta-data update issue? corrupt meta-data? > That's all very difficult to tell without having a backtrace or something more insight-giving then you can offer at the moment ( I understand that you don't know how to build the debugging kernel, though with a recent version of FreeBSD (like 7.0-RELEASE), debugging symbols are included in the "standarized" installation, if you put the following in /etc/rc.conf: dumpdev="AUTO" # Device to crashdump to (device name, AUTO, or NO). dumpdir="/var/crash" # Directory where crash dumps are to be stored you should be able to get a coredump... see the developers handbook http://www.freebsd.org/doc/en/books/developers-handbook/kerneldebug.html Cheers, Remko -- /"\ Best regards, | remko@FreeBSD.org \ / Remko Lodder | remko@EFnet X http://www.evilcoder.org/ | / \ ASCII Ribbon Campaign | Against HTML Mail and News
