A380s b748s and 777s equipped with ge-90 have been known to cause wake turbulence for subsequent narrowbody aircrafts behind them. A separation amounting min of 3-4 minutes or more for departure and approaches is required. Widebody to widebody may be lesser.
As for KUL there was definitely bad weather during that hour. What I noticed for Sabah on whenever there's weather every traffic will be holding and Ak will always be the one to requesting to attempt an approach. Once an ak has landed u see other traffic's such as MAS, China southern and xiamen airlines and the koreans will request to try out. If the ak goes around everyone continues to hold until the weather dies out. Lol
