Web control panel becomes unresponsive

[ex313]

I see it on occasion where the web interface will become unresponsive. I try to close the browser and log back in but no response from the router. Internet access is still up, so the router hasn't locked up. I usually end up having to power cycle it to get things back.

Any thoughts on what to troubleshoot?

Trying to upload a syslog file but the forum is not letting me.
