The issue seemed to happen again. This time the only errors printed in dmesg are the following:
[14079.778092] [PF_RING] Unable to activate two or more ZC sockets on the same interface eth1/link direction [14079.790079] [PF_RING] Unable to activate two or more ZC sockets on the same interface eth1/link direction [14079.814090] [PF_RING] Unable to activate two or more ZC sockets on the same interface eth1/link direction [14079.826089] [PF_RING] Unable to activate two or more ZC sockets on the same interface eth1/link direction [14079.850091] [PF_RING] Unable to activate two or more ZC sockets on the same interface eth2/link direction [14079.862091] [PF_RING] Unable to activate two or more ZC sockets on the same interface eth2/link direction There are no errors about TX hang and the software never tried to reopen the sockets so this confuses me.
