It's most likely a software issue. I was able to keep it from filling the logs by installing a logging discriminator that matches a regular expression filter like so:   logging discriminator PACKET mnemonics drops _Packet is neither ipv4 nor ipv6 log...

We too are seeing this with version 157-3.M1.bin but how can we filter these from eating up our syslog and spewing to the terminal? We are seeing them every 10 seconds.
