I will give 2.6.9-bb4 a try tomorrow. However, I am now noticing some
interesting behavior (now that I'm paying closer attention). Both of my UML
instances will start consuming massive amounts of CPU time on the host
machine at some "arbitrary" point.
Once this starts, I can log into the machine without affecting behavior (via
"screen -r <instance>"). However, once I do ANYTHING ("ps -ef", "uptime",
etc) the bind daemon disappears. This was most noticable when I launched a
"ps -ef ; ps -ef". In this case, the first listing showed the following:
UID PID PPID C STIME TTY TIME CMD
named 8563 1 0 02:24 ? 00:00:00 /usr/sbin/named -t
/var/lib/named -u named
named 8564 8563 0 02:24 ? 00:00:00 /usr/sbin/named -t
/var/lib/named -u named
named 8565 8564 0 02:24 ? 00:00:10 /usr/sbin/named -t
/var/lib/named -u named
named 8566 8564 31 02:24 ? 02:13:11 /usr/sbin/named -t
/var/lib/named -u named
named 8567 8564 0 02:24 ? 00:00:01 /usr/sbin/named -t
/var/lib/named -u named
The second ps listing was missing the named daemon. Its also interesting
that this happened less than 4 hours after I had reboot the UML (notice the
'TIME' column). Are there some actions I can take with the host to diagnose
what is happening during these "episodes"? All of my UML instances running
bind seem to exhibit this behavior.

I'm afraid not. I know that the host is SKAS enabled, but I'm not certain of
the version.
