Have you considered it might be an Azureas issue?
Older Azureas clients have caused me many headaches
on my home network.  I understand your network is
much more robust than what I am running on.  However,
Azureas runnign on MS Windows XP clients caused network
problems which affected my FreeBSD installation.  I never
did trace the cause except that when Azureas went away so
did the problems.  The newest Azureas client seems to play
much nicer though and I haven't been experienceing any
network issues.  The symptoms you describe sound very
similar in general to the ones everyone on my network
experienced, albeit with different applications in play.
