Panic in logs

Channels DVR Server

Assuming this is just a network related thing, but I thought I’d mention it. I noticed this in the logs today:

This is on a Synology DS-916+. The only thing out of the ordinary I did today was to install DSM 6.1.3-15152 Update 1, which did not require a reboot. I did that at probably 9am or so.

Edit: it’s not clear what 192.168.1.3 actually was in this case - the NAS is .1.200, the router is .1.1, and I don’t see any devices at the moment that are on .1.3. I was connected earlier, but I believe my VPN uses 192.168.2.x…

Edit 2: I think .1.3 was my Apple TV. No one was at home, so presumably it was on standby…

I’ve seen other reports of this. It’s mostly harmless. It’s coming from the Top Shelf, presumably right before the ATV goes to sleep (and this is unable to download the data it requested)

Ah - gotcha. Thanks!
