As shown in the pcap file https://bugs.mageia.org/attachment.cgi?id=3304 after a period of time ranging from hours to weeks, the driver starts replying to syn,ack messages with reset, instead of ack messages. Rebooting corrects the problem, as shown by the pcap file https://bugs.mageia.org/attachment.cgi?id=3305
Probably not via-rhine related at all. The driver doesn't do the TCP processing, that is done by hardware independant networking code. You need to look at the open connections, and other statistics. Useful information: lspci # shows hardware info dmesg # shows kernel log messages config used to build kernel ss -a (or netstat) shows open connections
Thanks for the quick response. Next time it happens, I'll add the additional information.
Created attachment 90521 [details] Output of lspci, zcat /proc/config.gz, dmesg, ss commands I was out when it happened again. As shown, during the two hours since outbound connections stopped working, dmesg was overwritten by a spammer. The ss output looks normal for this system, where I'm using ssh to connect to it, and have a couple of other systems using autossh to connect to it, so that I can connect to them. After reporting the bug, I switched to kernel version 3.4.24-server-2.mga2
Created attachment 91411 [details] dmesg output Now that it's happened again, I've been able to get proper dmesg output, but as shown, there are no error messages being generated related to networking.
