[Mono-dev] ASP.NET apparently leaking semaphores

I started with mono rpm's for 2.6.7 a while back but had had some  
issues both with leaking semaphore arrays (i.e. more and more  
accumulating in ipcs) and some incompatibility with ASP.NET MVC2, so I  
built 2.8 from source. The leak continued, so I just built 2.8.1 from  
source and the same thing is happening. This is on an Amazon AMI (i  
guess it's centos under the hood). The symptoms are that semaphore  
arrays keep building up and if i don't manually remove them with ipcrm  
after a while requests to ASP.NET pages return no content with no  
errors in the logs. Since I can't find any mentions of this happening  
to anyone else, I assume it's not general ASP.NET bug. Any ideas how i  
can troubleshoot this further?
