[galaxy-dev] Galaxy server requires a restart to activate tools

Hello, I have a fresh 17.01 Galaxy installed and set up with uWSGI. After installing a new tool, I can't run it without first restarting Galaxy. This is odd, because I know in 17.01 that should no longer be happening.

The error I get is "This tool was disabled before job completed. Please contact your Galaxy administrator.

In the logs I see "Tool (... tool name) removed from tool config, unable to run job Cleaning up external metadata files Error checking job readiness"

After Galaxy restarts, the tool runs fine.

Is there anything typical that could cause this? Any place I should start looking?

Thanks!
