Will logRotate cause any unavailability in MongoDB service? In another question, I've mentioned that how would I rotate logs in MongoDB Replica Set installed in Windows Server. However, it seems there's no built-in way to get it automatically on Windows - only with 3rd party tools.

That being said, I was wondering what would happen if I connect into MongoDB and execute 

use admin
db.runCommand( { logRotate : 1 } )


Will it cause any unavailability in MongoDB service? Or will be just a matter to stop log capture for couple seconds and start writing in the new file?
The should not be any break in service. Just remember set systemLog.logRotate or --logRotate to rename or it will open same file again...
