Running DRAT on a Mac - Frequently asked Questions (FAQ)

Ulimits

If you are running on a Mac on 10.12 (Sierra) or newer, you may run into some issues with the default open files and num proc settings (also known as ulimit). The default ones for Mac are pretty paltry, and since Apache OODT (as of version 1.3, currently what's pinned to DRAT) uses XML-RPC which in turn has the potential to use up a lot of sockets (especially with Proteus which makes lots of Ajax call backs), you may be running into issues using the DRAT GUI.

Check out this page to see how you can increase the file limits to something that Proteus can run under.
