>I seem to recall that having debugging enabled can cause this? Check the 'debug' attribute of the compilation tag in web.config.

Debug is set to False. Here is the top of the Web.config file.

<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
	<appSettings/>
	<connectionStrings/>
	<system.web>
		<identity impersonate="true"/>
		<compilation debug="false" targetFramework="4.0">

So, I will have to do some research as to know what else could be in effect here.

>You can also change the number of recompiles before a recycle - quick search indicates that it's the numRecompilesBeforeApprestart attribute in machine.config. But doing that would really just be avoiding the issue without knowing the cause.....

I agree.
