NI-4100 problem

There were reported issues with the NI41xx firmware causing IP drop-outs earlier this year - are you running the latest version?

If its a leak in the code, try compiling without the EIB module - do you still loose IP connections, if yes then there is something in the master code that is eating mem, otherwise its with the EIB module / UI code. It could also be overrun with messages / feedback.

What is your Volatile Mem, NonVolatile Mem & Duet Mem?

Please also check the URL list of the master. Maybe there is a entry to the IP of itself. This loop will overrun the IP handler, and so you'll loose IP connections.

the following urls exist in the url connection list

IF 192.168.1.200 is the master itself, remove the URL entry - loopback!

I had a similar issue on an NI700 with slow upload speeds and erratic behavior, turned out to be a wire got crossed on the network cable.

Can you use a serial cable to connect to the program port on the processor? If so, check the memory available on the processor. If it is low, it will probably be a memory leak in your code somewhere. This is where I would start checking. If it does look like a memory leak, the best way to troubleshoot is to pull up diagnostics and see if there are a bunch of messages about the available memory dropping. If you don't see this happening on it's own, start pushing buttons and see if you can figure out when it happens. If you do see it happening, start commenting out code the is running in mainline or at regular intervals (timelines, modules that poll, ...)

Hope this helps,
