I have installed netspeed_applet-0.12.1 and the <right click on applet>->Device Details: "Bytes in" counter wraps to 0 once it reaches about 4Gb. This can be tested by selecting the applet to monitor lo, ssh-ing into localhost and doing a cat /dev/zero.

Same with 0.13.
I have forwarded this message upstream to mfcn AT gmx DOT de, the maintainer of netspeed_applet.
This is the response I got from the maintainer. ----paste---- Hi, I don't have an account in the gentoo bugzilla. Here is what I know: - the 4 GB limit is because the counter is an unsigned int32. - until recently this was actually an kernel issue - probably it still is. check /proc/net/dev. if it contains "non-wrapped" values, then the bug should be in libgtop2. - if the bug is in libgtop2, someone should fix it or at least report it ;) - this bug is almost certainly not in netspeed, since it already uses unsigned int64 for the byte counters. So as soon as the the underlying stack (kernel + libgtop2) use 64 bit integers for the counters, this should just work. Regards, J

Thanks for the help. Seems /proc/net/dev is wrapping too, so this is an upstream kernel problem. Closing.
