Hi,

These errors are because the JVM has run out of memory.
You will need to increase the heap size for the jvm.

Also, the full release of 1.2 has additional memory optimizations that should eliminate these issues.

(Although if you don't use one of our 1.2 bundles you will have to perform the heap size change manually).

-Xms128m -Xmx512m -server
