Since 1.9.2 bungeecord support was released, my bungeecord server is getting 100% CPU usage several times during the day. No DDoS attack or bots is detected, no error in log is appeared. In htop (linux debian) there is like 8-10 instances of bungeecord using 100% CPU, so 600% overall. Server cannot be stoped regularly from bungeecord console, because it's not responding. I have to kill the process with SIGKILL flag. Screen: http://www.michalvanek.net/s/20160515181729.png Using latest bungeecord build 1155. Server has around 40 players online, bungeecord instance has allocated 1GB of RAM.

Thank's for answer. Reported this issue to github: https://github.com/SpigotMC/BungeeCord/issues/1869
Are you on the latest Build of BungeeTabListPlus? It's quite cpu intensive. Try running Bungee without XmX. If it doesn't help, get a VisualVM report as requested by Jamm14. There are plenty tutorials how to make one in the internet.
