jenkins just tripped a similar issue... the problem here seems related to a
very lowish rambuffer together
with flushing by docCount. I was not able to reproduce it yet.
each time this fails ram buffer is 0.1M and maxBufferedDocs is 3 so
something seems to break the assert if we flush by doccount and not
necessarily take the largest DWPT out of the loop
selckin can you reproduce these errors? I just added some more info to the
assert so if you run into it can you past the output?
