For some time, probably since I upgraded my BI computer, I have been seeing "Socket error" messages in BI Stats Messages for all my IP cameras. This message usually appeared in BI Stats Message between 1-2 times during the day along with Watchdog resets on my Loftek camera.
My understanding of what a "Socket error" represents is some sort of network communication error. This didn't make a lot of sense to me because all my network cables are CAT-6 (solid wire) and passed all stress tests for gigabit. All my cameras, gigabit switches, wireless router and BI PC are connected to APC battery backup unit(s). So, no power outages should effect my cameras, switches, wireless router or BI router. As long as they don't exceed 20 minutes.
Everything seemed to point to a possible problem on my BI PC. So, I made sure that I was using the latest network drivers for Windows 7 and verified that power management was disabled for Sleep, Hard drive, network adapter, etc. A few days ago, I disabled "Green Ethernet" and "Energy Efficient Ethernet" in my network adapter settings and POOF my "Socket error" messages and "watchdog" messages are gone. So, it has now been two days without any "Socket error" or "Watchdog" message in BI Stats Messages. See the attached pictures below for how to disable "Energy Efficient Ethernet" and "Green Ethernet".
Definition of Energy Efficient Ethernet
/ Green Ethernet
Energy-Efficient Ethernet is a set of enhancements to the twisted-pair and backplane Ethernet family of computer networking standards that will allow for less power consumption during periods of low data activity. The intention was to reduce power consumption by 50% or more, while retaining full compatibility with existing equipment. The Institute of Electrical and Electronics Engineers (IEEE), through the IEEE 802.3az task force developed the standard. The IEEE ratified the final standard in September 2010. Some companies introduced technology to reduce the power required for Ethernet before the standard was ratified, using the name Green Ethernet.
