DayZ keeps freezing for 2-5 mins and then comes back

[Patient101 0]

Whenever playing DayZ I find that it keeps on just freezing, sometimes for not very long and sometimes for up to 5 minutes which means that the whole experience of playing the game is ruined. While the game is actually working I have no problems with lag or juddering however it sometimes just freezes and I don't know what to do about it. Any help would be appreciated.
