System.IO.IOException: Too many open files

问题

I'm getting this error intermittently when debugging my ServiceStack web app on Mac OS X.

I can't seem to pinpoint what it is, I've tried killing the xamarin web server by using this command:

ps aux | grep xsp4 | grep -v grep | awk '{print $2}' | xargs kill -9

I've tried renewing my DHCP lease and clearing my DNS cache. Even tried restarting the entire Mac.

Mind you there doesn't seem to be anything wrong with the code, because when I run the Xamarin web server manually with this command:

xsp4 --root ~/Development/PROJ_FOLDER --port 8080

it works fine... I only see the issue when I run the application from Xamarin Studio.

Any ideas?

回答1:

I solved a similar issue by disabling Mono's file watcher due to a bug.

In the terminal:

export MONO_MANAGED_WATCHER=disabled
