Linksys Wireless Router :: EA4500 Breaks Bonjour / Zeroconf After A While?

After some time of usage (typically days), I notice that Bonjour networking degrades. That is, the various Apple computers on my network can no longer see each other via Apple's Bonjour protocol. They can still connect directly using IP addresses however. The only solution seems to be a reset of the router. Are there some detailed logs I can look into to determine what the problem may be? The logs shown in the web interface don't seem detailed enough.
