I Installed Server.app on Yosemite to enable caching, but see many server processes in Task Manager (_xcsbuild and _devicemgr and _calendar processes) _xcsbuild and _devicemgr and _calendar processes seem to be the bulk.

None of them are using significant rescues but there are dozens.

How do I identify the launcctl jobs and turn them off?
You can stop the _xcsbuild "session" by running sudo xcrun xcscontrol --shutdown. This will also stop it from starting at launch.

Although it's probably a better idea to use xcscontrol, the individual launchctl tasks are:


com.apple.xcsd.plist
com.apple.xcscouch.plist
com.apple.xcsredis.plist
com.apple.xcscontrol.plist


You can also delete all the remaining data by running sudo xcrun xcscontrol --reset.

I'm still looking myself for _devicemgr and _calendar, but just this one is enough to let you shut down/reboot without the warning.
