i don't know if this was the issue this time but the general issue where i end
up rebooting the vm host every now and again is this:

systems run for some time. the GUEST vm's at some point grind to a halt. not
quite a halt but it seems like any i/o causes some timeout. like "ls" on the
cmdline in a guest can take between 30 to 150 seconds. it doesn't spin using
cpu. it just hangs. it's like a timeout of some sore, then finally it works.
the system is not overloaded. the host machine is pretty much idle. as are the
vm's. you run top in one shell-in and do the ls in another - nothing is loaded
either there. it's as if i/o is doing something like logging and a dns lookup
or a connect is timing out.

now i have tried simply shutting down the vm in question and starting it again
- it stays "bad". i've shut down all vm's and started them again (it takes
forever thanks to the i/.o timeout issue) and nothing is fixed. the only thing
that fixes it is a reboot of the host os that brings all vm's down, reboots
the host os then starts them up and all is fine again... until the next time
this happens. i have rummaged around logs on the host and guests. i have looked
at every dmesg and more and i couldn't find anything telling me what was going
on. maybe i missed something but i only have so much time to spend on these
things before the simple "reboot the sucker" option needs to be used and we
have work to get on with.

it's not because of a build server overload - nothing is overloaded. fyi the
HOST os works just fine. no langs. i/o works perfectly. i just don't know what
it is. :(
