I  create an  object DF_403_TABLE for class ore.frame , I want to run dist(DF_403_TABLE) in ORE, but I encountered in ore runtime
"Error : cannot allocate vector of size***"

I read "I can" t analyze the or mine all of my data, it has to be the javax.media.sound.sampled "and
Oracle R Enterprise Documentation.

I thought ORE can deal with the problem of insufficient memory.
But why would still meet the  error above, how should I solve it, (through  sampled or additional memory)
Would you please tell me another way to get the result.

The environment that
Windows 2008, Oracle 11.2.0.4, ORE 1.4.1 64 bits
4 GBof OS memory
