Package: mtr Version: 0.82-3 Severity: minor Dear Maintainer,
As part of an effort to diagnose - and later to confirm the fix of - an ongoing network problem, I have maintained an mtr session running for several weeks straight. The current overall summary for one hop in that session presently reads as follows: Hostname Loss Rcv Snt Last Best Avg Worst StDev 73.223.7.1 0.3% 4028069 4039341 68 7 12 60593 -2147483.75 The standard deviation value is negative, which is meaningless AFAIK, and therefore should not be possible. The specific negative value in question looks at a glance like the result of an overflow. I am not clear on exactly what it would take to reproduce this problem. Presumably, unreasonably high worst-case ping times in what is otherwise a normal network environment would be at least a contributing factor. However, I am relatively certain that I recall past sessions where this hop has shown a Worst value of over 70000 milliseconds, but the StDev value has remained positive; as such, I am not sure whether that would be sufficient. This bug is of course extremely minor, as even if it does occur reproducibly, the circumstances for it are rare and it is unlikely to have more than a cosmetic effect even when it does occur. However, as it is still a bug, I felt it worth reporting anyway. If there is anything I can do to help to track this down, please don't hesitate to let me know. -- System Information: Debian Release: wheezy/sid APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-3-amd64 (SMP w/12 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages mtr depends on: ii libatk1.0-0 2.4.0-2 ii libc6 2.13-35 ii libcairo2 1.12.2-2 ii libfontconfig1 2.9.0-7 ii libfreetype6 2.4.9-1 ii libgdk-pixbuf2.0-0 2.26.1-1 ii libglib2.0-0 2.33.12+really2.32.4-3 ii libgtk2.0-0 2.24.10-2 ii libncurses5 5.9-10 ii libpango1.0-0 1.30.0-1 ii libtinfo5 5.9-10 mtr recommends no packages. mtr suggests no packages. -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
