I'd (very carefully) look at the DC voltages on the RS485. Yes you have the Zener diodes there, but something nasty is obviously getting through.
If you're killing that many devices I'd also look at opto-isolated RS485 transceivers. At least that way you can get it working, and then look at what the voltages are and try to determine why it kills parts of your system.
