[R] Error: OutOfMemoryError (Java): GC overhead limit exceeded

[jim holtman]

On the off-chance, are you using XLConnect or xlsx packages that are using
Java to access the spreadsheets?  If it is XLConnect, are you access the
'.xlsx' style workbooks?  If so, can you try using '.xls' workbooks?  This
is a problem that I have had; the '.xlsx' workbooks take a lot more
resources (CPU and memory) to process.

A little more information like what your sessionInfo is would help a lot in
responding to your problem.

What is the problem that you are trying to solve?
Tell me what you want to do, not how you want to do it.
