Apache throughput turns glacial on weekends

["McAdams, John" <john.mcadams@xxxxxxxxxxxxx>]

My Apache/2.2.19 server running on a Windows 7 machine mostly seems to
run fine.

 

But on weekends, sporatically, throughput turns glacial.  It hasn't
crashed, and after a long wait it will serve up a page, but it's
basically of no use.

 

When I check my error log, I find multiple (hundreds, at least) errors
saying:

[Sun Jun 26 16:33:11 2011] [warn] (OS 64)The specified network name is
no longer available.  : winnt_accept: Asynchronous AcceptEx failed.

Any ideas or suggestions?
