C# Webservice, sometimes error

[skiflyer]

I'm seeing the following error in my apache log...

 client denied by server configuration: /path/to/php/file.php

When my C# program uses SOAP to access the file.php

But the oddity is that I don't always see it, maybe 40% of the time it pops up. I can't think of any settings that would cause an intermittent problem like this, any ideas?

I'm not too sure this is a server issue as much as a 'sessions' issue. Is this problem specific to one client or does the same thing happen regardless of the machine you use to access this page? Check your error logs for the date and times that this happens and see if this puts any light on the issue.

I think it's a sessions issue too, since it happens with two quick calls to each other. Adding a second worth of sleep is appearing to clear it up (after 1 day of testing anyway).

It happens from all machines and connections.
