I've had the same problem on RH9 with mono beta 9 and I came to decision not to use AppDomains (and rewrite all existing code on the basis of System.Diagnostics.Process) in Mono for the future as it's a great source of errors and headache... :-( There're a lot of errors over there I think... for example it's impossible to create AppDomain with GC turned off... sometimes unloading of AppDomains doesn't work properly... sometimes I get strange errors and warnings when working with AppDomains... and so on...
But, if you still want to run your example on RH9 try to turn off the NPTL! To do this compile Mono sources like this: ./configure --prefix=/your/installation/path --with-nptl=no make make install Best regards, Vadim B.
