OpenSprinkler Forums Hardware Questions OpenSprinkler Controller lockups / crashes with wired Ethernet module Reply To: Controller lockups / crashes with wired Ethernet module




I forgot to mention one thing… I’m not convinced that the crashes I’m seeing are related to DNS timeouts. The forum member who posted about using a VLAN to solve the problem hypothesized that there’s some device on his network that sends a particular type of traffic that the software based TCP/IP stack on the ethernet module chokes on, this causing the crash. By removing all other network traffic from the link to the OS controller, it never sees this sequence that sends it into a tailspin and it stops crashing. If taking your IP camera off the VLAN solves your problem, that would give us a huge clue about the problem, and make it much more likely we could isolate the cause of the crash.
