Hello, I am a software developer for a video surveillance application and also a client of NIS for a few years.
Recently I installed NIS 2010, and now my video surveillance software is experiencing a memory leakage problem (it wasn't in NIS 2009). The IP camera that is involved is accessed over the TFTP protocol which doesn't guarantee the delivery. The memory leakage happens when I use this camera ONLY (camera that uses TFTP protocol)
I believe that the situation is as follows:
-appears some UDP packets are not received, causing the entire video frame (40-60 Kb in size) to be incomplete.
-The software therfore drops the frame and then starts receiving the next frame.
However, NIS still keeps waiting for failed frames to arrive, holding the data received in memory.
As a result, the software memory usage grows and it has to restart itself every 10-12 hours.
