Freeswitch cpu 100% usage -- 2

I have a bigbluebutton server with greenlight with 0 users in room, freeswitch starts using 20-40% cpu and X minutes after raises to 100% for some minutes and then go back to 20-40% with no reason at 0 users. This is a weird error/bug due to I have other 30 servers with the same configurations and all of them are okay but sometimes a server starts with that same error, so THIS HAPPENS IN ANY SERVER WITH NO REASON. I need someone that can replicate this error and then solve the issue.
