--- Begin Message ---Package: mbuffer Version: 20140310-3 Severity: important Tags: upstream Dear Maintainer, I traced a failure in my homebrewed backup system to a bug in mbuffer. Intermittely, a backup would hang; strace showed that mbuffer was waiting forever printing the statistic in @ 0.0 KiB/s, out @ 0.0 KiB/s, 0.0 KiB total, buffer 0% full I eventually determined that the following command would reproduce the problem almost every time: $ echo | taskset -c 1 mbuffer -P50 In this case, mbuffer should exit essentally immediately. I believe that the problem has something to do with the way mbuffer uses threads. By not using "taskset -c 1", the problem manifests more rarely, though still more than 1 in 50 times. The bug seems to exist in unmodified upstream mbuffer-20141227 as well. Curiously, the bug does not exist or does not manifest nearly as readily on FreeBSD 9.2 with unmodified upstream mbuffer-20141227. -- System Information: Debian Release: 8.0 APT prefers testing APT policy: (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages mbuffer depends on: ii libc6 2.19-13 ii libmhash2 0.9.9.9-7 mbuffer recommends no packages. mbuffer suggests no packages. -- no debconf information
