ARP time outs on 2960x - troubleshooting.

I'm experiencing a strange issue. Some devices on a specific VLAN drop off after a period of time for no apparent reason. The server won't see the device until you SSH into one of the MDF switches, ping the culprit, and it brings it back online. There's only a few things I can think of - either the device isn't smart enough to bring itself back online after the dead timer, or there's a bug in the code on the switches I'm using. Has anyone ever ran into this issue?
