I notice network traffic spikes on my LAN from time to time. I was able to use the Resource and Performance Monitor tool in Windows 7 64-bit edition to determine it was "System" image using various local ports (1059 or 1063) and talking to my NAS (Synology DS209) box using remote port 445. The amount of data flows various, but I did capture a few screen captures with the following activity:
Send (B/sec) Receive (B/sec) Total (B/sec) 136,493 8,662,937 8,799,430 7,631,482 8,400,968 16,032,450
I did check to make sure the no indexing was being performed on the network drives and I didn't see anything. I have Norton Antivirus, but I don't think that is causing the issue.
When this network traffic is active, it does slow my internet traffic as webpages will take longer to load. I don't notice any spikes in CPU usage during these times.
I have been unable to find anything that describes what is going on. I don't know the period at which triggers the activity, but it does seem to happen a few times a week. It could occur during the day, but since I am at work I am unsure.
Does anyone know what this activity might be and if so, can it be turned off safely?
