Umbraco version: umbraco v 4.0.0 (Assembly version: 1.0.3327.20280)
Asp.Net: .Net framework 2.0
Windows server 2008 with IIs7
Sometimes when viewing a page with a contained macro, the macro part of that page is completely removed, not rendered, no error no nothing only a incomplete page. Loading the same page again, it's rendered correctly. This occurs very rarely.
When investigating more deeply I found out that this is somehow connected to the recycling of the application pool in which umbraco is running in. Setting the application pool to recycle itself every 1 minute I could reproduce the behavior more often than with the default recycling time but still not consistently after every recycling.
I was never able to reproduce the error when adding the umbDebugShowTrace=true, the page always renders correctly when having it set to true.
Has anyone got a clue about what can cause this or have anyone seen this before?
Note. It just not a particular page with a macro the got this behavior, every page on the site that have a macro on it acts like this when the problem occurs.
