aspnetcore: Server Hangs on OS X, RC1, HelloMvc

On El Capitan using the following Dot Net Env:

1.0.0-rc1-final    mono                    linux/osx mono

I checked out this sample: https://github.com/aspnet/Home/tree/dev/samples/1.0.0-rc1-final/HelloMvc

Then, using 1.0.0-rc1-final mono, I ran:

dnu restore
dnu build
DNX_TRACE=1
dnx web

When navigating to http://localhost:5004 I get the following output, and the server just hangs indefinitely

@Eilon Can we close this bug? It seems to attract “me too” posts without being sure they are 100% related to the bug that was opened 6 months ago with no new updates from the original poster.

I suggest that people who have similar issue would need to reopen a new bug with their own repro steps.

@sec That worked for me - thanks. Built on OSX, run on Ubuntu 15.10, unless I do “export MONO_THREADS_PER_CPU=2000”, it just hangs. Am on Mono 4.2.1.

Using Mono 4.2.2, try this: export MONO_THREADS_PER_CPU=2000 Also on FreeBSD this helps: export MONO_MANAGED_WATCHER=yes
