Package: collectd Version: 5.1.0-3 Severity: important Tags: patch Dear Maintainer,
When using the mysql plugin, if the queries it polls from the mysql server do not return results, then memory is leaked. This was fixed upstream in https://github.com/collectd/collectd/pull/263 during the wheezy freeze. -- System Information: Debian Release: 7.8 APT prefers stable APT policy: (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/1 CPU core) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages collectd depends on: ii collectd-core 5.1.0-3 ii iptables 1.4.14-3.1 ii libc6 2.13-38+deb7u6 ii librrd4 1.4.7-2 Versions of packages collectd recommends: ii libc6 2.13-38+deb7u6 ii libcurl3-gnutls 7.26.0-1+wheezy12 ii libdbi1 0.8.4-6 ii libdbus-1-3 1.6.8-1+deb7u5 ii libesmtp6 1.0.6-1+b1 ii libgcrypt11 1.5.0-5+deb7u2 ii libgdk-pixbuf2.0-0 2.26.1-1 ii libglib2.0-0 2.33.12+really2.32.4-5 ii libhal1 0.5.14-8 ii libmemcached10 1.0.8-1 ii libmodbus5 3.0.3-1 ii libmysqlclient18 5.5.40-0+wheezy1 ii libnotify4 0.7.5-1 ii libopenipmi0 2.0.16-1.3 ii liboping0 1.6.2-1 ii libpcap0.8 1.3.0-1 ii libperl5.14 5.14.2-21+deb7u2 ii libpq5 9.1.14-0+deb7u1 ii libprotobuf-c0 0.14-1+b1 ii libpython2.7 2.7.3-6+deb7u2 ii librabbitmq0 0.0.1.hg216-1 ii librrd4 1.4.7-2 ii libsensors4 1:3.3.2-2+deb7u1 ii libsnmp15 5.4.3~dfsg-2.8+deb7u1 ii libssl1.0.0 1.0.1e-2+deb7u14 ii libtokyotyrant3 1.1.40-4.1+b1 ii libupsclient1 2.6.4-2.3+deb7u1 ii libvarnishapi1 3.0.2-2+deb7u1 ii libvirt0 0.9.12.3-1+deb7u1 ii libxml2 2.8.0+dfsg1-7+wheezy2 ii libyajl2 2.0.4-2 collectd suggests no packages. -- Configuration Files: /etc/collectd/collectd.conf changed [not included] -- no debconf information
