PLM Lifespan

I've had my ISY for a couple of years now. My first PLM was a 2412S rev 3.3. It started acting quirky a year or so ago and I was getting poor communication and failed writes. I bought a new 2412S which turned out to be a rev 3.1 (don't ask me - must have been old stock?) It worked fine until last week. Last week that one failed completely to the point where ISY only starts in safe mode.

I've reverted to my old PLM to get up and running again. To be honest I'd forgotten it wasn't working right so I pulled my hair out for a couple of days trying to troubleshoot the problems. I remember now, though, that it was fubar so I've given up on using it.

Has anyone else had issues with PLM failure/bad PLM function?

I know they've dropped the 2412S in favor of the 2413S now. I'm hoping it's more reliable as 2 PLMs in 2 years seems unreasonable. I haven't read the specs on the 2413 but I remember when they first came out they were capable of far fewer links than the 2412. I hope that's not the case now as my 2412 had well over a thousand links in it.
