Hello there DayZDevTeam!
It has been brought to my attention that it's possible to significantly slow down a server's performance and eventually crash it completely by using gift boxes. This is done by putting gift boxes inside medical bags and then put that medical bag into another gift box and vice versa. If the person who has the "glitched" gift boxes/medical bags on them leaves the server, it returns back to normal performance. When they join back in the server slows down once again. This happened on the **0.62.143758 stable version** of DayZ.
