Problem: When previewing attributes or test executing operations that involve large amounts of data in Unwired WorkSpace, for example, either a large number of rows, or large object in the returned result, Unwired WorkSpace can run out of memory and crash.
Solution: Either do not preview or test execute large results, or increase the java VM argument -Xms, and -Xms in the UnwiredWorkSpace.bat file to increase the memory(heap) size and restart Unwired WorkSpace.
