Why do i get stuck on snapshots: entities

As question asks

Why do i get stuck on snapshots: entities

the problem is that if i go on a new server i have no problem but as soon as i log off then back on again to the same server i get to this and no further, it just sticks there

     LOADING 

SANAPSHOTS 85 ENTITITES :508

Numbers change every time off xcourse

As any one else got this problem or now what is wrong thx

I had this problem. Happened when I only had 4GB memory. Increased memory and the problem went. Could be coincidence.

Ummm ive got 8GB but i dont always get the problem its just after updates usually
