Adam, thanks for the response! With that, I'll mark it as Confirmed.
The symptoms all seem to center around the order that modules are loaded
and perhaps how networking is handled. Perhaps keepalived needs to be
delayed until after all networking. I have to wonder if this still
affects 12.04, since runlevel 2 is now delayed until all interfaces in
/etc/network/interfaces have been brought up.

Title:
keepalived using genhash keeps getting "zombied" and using CPU to a
100%
Status in “keepalived” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: keepalived
When using keepalived last version from Dapper, when it has a genhash
failure on http service check it keeps writing every second to logs
filling the hard drive, using 100% CPU and the checker get "zombie". A
restart of the process does not work on it, and if it happens on the
master server, it also starts on the slave server, making the service
unavailable in 90% of the requests. I installed by hand compiling
1.1.15 and problem goes away for now, with 1.1.14 the issue still
happens.
