Problem with high bandwidth callouts

[Jim Skon]

Hello,

I have been developing a modification to the 802.11 driver to support a
version of PCF (polling mode).  The AP part of this solution depends on
several active callouts to time the operation of the protocol.  The
problem I am having is that after several hours of stress testing
(pushing the system at maximum bandwidth), the system appears to start
losing set callouts.  The callouts are still active, and past due, but
are never called.

I have already done similar implementations in the netbsd and linux
environments, and have never had such a problem.

Note that I am setting callouts (only 3) at a rate in the 100's per
second, so a lot is going on.

Has anyone ever had such a problem?

Thanks!
