Package: incron Version: 0.5.12-1 Severity: important Tags: patch Dear Maintainer,
After updating two machines from current stable to buster I've got a lot of zombie processes caused by incron. It looks like this known issue and was already fixed: https://bugzilla.redhat.com/show_bug.cgi?id=1656939 I'm attaching copy of patch from Fedora package that fixes this issue for me. It would be cool to have this applied to Buster release -- System Information: Debian Release: 10.0 APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.1.9 (SMP w/8 CPU cores) Kernel taint flags: TAINT_WARN, TAINT_OOT_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages incron depends on: ii adduser 3.118 ii init-system-helpers 1.56+nmu1 ii libc6 2.28-10 ii libgcc1 1:8.3.0-7 ii libstdc++6 8.3.0-7 ii lsb-base 10.2019051400 incron recommends no packages. incron suggests no packages. -- Configuration Files: /etc/incron.allow [Errno 13] Permission denied: '/etc/incron.allow' /etc/incron.deny [Errno 13] Permission denied: '/etc/incron.deny' -- no debconf information -- WBR, Dmitry
