Ufuk Celebi commented on FLINK-1465:
------------------------------------
I guess it is an overflow of some sorts. The OoM exceptions are caught in
rethrown to actually give better error messages. Should we keep this or just
skip it?
Do you know what the misconfiguration was? For the network buffer pool, only
page size and number of pages should be relevant.
