[IronPython] Sandbox AppDomains and 'Object has been disconnected or does not exist at the server' exceptions

[Patrick van der Willik]

I isolated my IPy instance into a seperate AppDomain with some serious 
restrictions on which assemblies are allowed to be loaded. In the 
current setup it's impossible to open sockets or read files from disk, 
which is exactly what I'm trying to accomplish.

However, when my server is idle for a few minutes(or more simple, when I 
put my laptop into hibernation and resume it later that day), the 
connection with the appdomain seems to time out. When calling a function 
it'll throw an exception with the following message:
"Object 
'/0bb4e678_d665_4698_ae30_cdaf28351e72/0jpmcrorxe_qkvj6fml9kboj_3.rem' 
has been disconnected or does not exist at the server."

I'm not really sure how I need to solve this one. Research showed that 
it probably has to do with Remoting.
