The problem that you have encountered is quite strange. We tried to reproduce it, but to no avail. Have you configured your project to run in a Web Farm/ Web Garden environment?
Please specify the changes that should be made to the setup that I provided in my previous post in order to recreate the issue, if there are any. You can also send the module that you are using so that I can examine it locally. Additional information about specific settings that are configured in your project could be useful for determining the cause of the problem at hand.
