RB532 ping timeout?

I have a RB532 with a single SR9 card connected via Ethernet to an AMD XP 2600+ server running RouterOS (all Intel Pro/100 cards). More and more frequently, the Rb532 will lose connection and the watchdog reboots it.

This causes a 2-3 minute interuption to our wireless customers, and probably shouldn’t be happening.

I’ve tested and replaced the ethernet, but this is still happening. Any suggestions?

Thanks,
