So anyone else have periodic map exports (to feed a web site for static viewing) that seem to cause random instability? I have one set to export every 5 minutes and it seems like every 4th or 5th export, random devices on the network go yellow then back to green when export finished. Identified it when I set the export to every minute - I thought my network was being DDOS'd! Turned off export, all good. Set back to 5 now and see the periodic squirelliness as before. (Server 2003, Dual Xeon, 4 GB RAM, task manager all good). DOS window open and pinging on the same server shows no drops or latency and the devices it reports as unstable are pinging away like normal.

They certainly have some IO issues. I think the Data IO routines are mixed with the probe IO routines and that is why things are interesting.
