[users@httpd] Apache throughput turns glacial on weekends
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:
<quote on>
[Sun Jun 26 16:33:11 2011] [warn] (OS 64)The specified network name is
no longer available. : winnt_accept: Asynchronous AcceptEx failed.
<end quote>
Any ideas or suggestions?

Better approach is to put after these two:
#EnableMMAP off
#EnableSendfile off
#Enter this just after the above two
Win32DisableAcceptEx

As a person who's not a real techie, I just wanted to thank people on
this list for the advice that has solved my problem.

You may as well go ahead and uncomment EnableSendfile, so it reads
#EnableMMAP off
EnableSendfile off
Win32DisableAcceptEx
if you are running anything other than Windows Server... all of the
home/premium packages now have a corrupted TransmitFile() which will
only deliver two files at once; the rest of the requests may stall.

Yes. It implies that those two items are disabled or are not read by
the apache. It is by default. You need to search for this item in your
file. they are all together in line: 455 and 456 but it may be
different in yours because I have done many changes to my file.

No. Not without first reading and understanding the docs!
Those are set to off by default because they can sometimes
be associated with other problems. Especially sendfile
on windows! Off is the 'safe' setting.

OK, so I need the "#" in front of the first two commands?
So it should be:
#EnableMMAP off
#EnableSendfile off
Win32DisableAcceptEx
Correct?

Thank you!
I'll report back on whether this works. Although, it might be a couple of weeks before I become confident it has worked.

Put this code at the end of your configuration file.
<IfDefine AEX>
Win32DisableAcceptEx
</IfDefine>
It should work.
The configuration file is normally at:
[../apache/conf]

Looks plausible, since I found stuff online about anti-virus software causing problems, and this mentions that this is the underlying problem with that.
But just to show you what a techie I'm *not,* were do I put:
Win32DisableAcceptEx
The config file is the only thing I've changed. Is that just a command that goes on a line there?
