Motivation 1. Memory leak is quite serious problem even being controlled with MemoryObserver(still todo). De-facto it is show stopper at least for some of our clients. 2. We can't fix netsnmp memory leak quick enough due to complexity of the task. There is small probability that we could not fix netsnmp at all. The fix provides reasonable still temporary by nature workaround to win time for development appropriate solution. Change-Id: I2c3341d7826375859d9ebac58d0a627ab938752b
