I have not determined if the fault occurs after 10^15 or 2^30 bytes, but the former seems more probable. Perhaps the code does something like read from /sys/class/net/eth0/statistics/{rx,tx}_bytes into a 16 byte buffer, which would fail at 10^15. But a quick look through the network- manager source didn't turn up anything like that.
I'll provide the ifconfig output once the problem happens again. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1222377 Title: network-manager stops connecting to Wi-Fi after 1 PB transferred on any interface Status in “network-manager” package in Ubuntu: Incomplete Bug description: Transfer 1 PB or more over any eth* interface (not tested with lo, impractical to test with wlan*). Use ifconfig to confirm interface byte counters. Once a counter exceeds 1 PB, network-manager will fail to connect to any Wi-Fi access points, though existing connections will stay up. A single 10 Gb/s link can transfer 1 PB in two weeks.
