Can't reproduce on Linux (32bit Fedora 13)

could the problem be that we simply run out of memory?

Unni, is an error event dispatched? If so, what .code does it have?

Doesn't FileReader silently fail to read all the data on OOM in some cases?  See bug 604561 comment 22 (which I haven't had a chance to act on yet).

Jonas, No.. it does not seem to throwing any error event.It simply struck in the middle of the operation.I have added that as well in the case and updated.
What I feel is since the file load operation is memory intensive operation,it is really depending upon the system resource as it is told that the same issue was not reproducible in Linux(32bit Fedora 13).If that is the case, can we have alert or some message reporting back to user?.

Thanks
