My friend group has recently created a realm. It worked fine for around a week but now, no one can log on for more that 5-10 minutes before the realm disconnects us and resets any progress we made in the time we were on before disconnecting. The only add ons we have to the realm is the use of PureBDcraft texture pack but everything worked fine running it for 3-4 days. Nothing else we know of has changed to cause the crashing.
