try updating multiverse core to dev build 588 from here:

http://ci.onarandombox.com/job/Multiverse-Core/588/

you can also try the next build 589 but i have not tried that one.

this may work and it may not.

 

An alternative I would like to recommend would be MyWorlds, it uses less RAM, but has less features.

 

Got the same issue. Crashing every 6-7 hours, removing multiverse stopped it. Do you ever get crashes like this?
