Description

When this work-flow tried to download 10 big data files, it can finish part of downloading - maybe 6 and the rest 4 will keep busy. From log message, we can find something like:
Exception in thread "Data ecogrid://knb/IPCC.200735416582829.1" java.lang.OutOfMemoryError: Java heap space
Exception in thread "Data ecogrid://knb/IPCC.200735416192871.1" java.lang.OutOfMemoryError: Java heap space
Exception in thread "Data ecogrid://knb/IPCC.200735417143125.1" java.lang.OutOfMemoryError: Java heap space
Exception in thread "Data ecogrid://knb/IPCC.200735416271261.1" java.lang.OutOfMemoryError: Java heap space

When I increase the heap size of Kepler to 1.2G (current value is 5M), the downloading can be done without any problem.

I went to through the downloading code again, it seems to me we use input and out stream, so not sure why it uses so many memory.

If it is possible we can remove this work-flow from this release?
