net: invalid input packet!!!!!!!!! [ version 4.2.412.4]

[micmac0]

Describe the bug I have two nodes on testnet. One at personal home second is a contabo vps. Home computer never had problem since one week. The vps goes after some times (days) with spamming screen with only this message I think I got it 3 times in this node :

net: invalid input packet!!!!!!!!!
net: invalid input packet!!!!!!!!!
net: invalid input packet!!!!!!!!!
net: invalid input packet!!!!!!!!!
net: invalid input packet!!!!!!!!!

All my log file just contain this message. I don t have other info than this one.

Screenshots Looks also at log generated very fast + look gap between 71 and 80 and also datetime of all files. Only few seconds have been waited between these two ls commands :

Hello, ideally both log messages should not appear. Currently they're under investigation. Anyway do not worry about, only make a report if you continue observe messages after next upgrade. Thank you!
