Package: logcheck Version: 1.3.18 Followup-For: Bug #657641 Hi,
this problem still exists in current versions, I just ran into it. It seems to occur when there are a large number of log lines to process, so that the previous run of logcheck is not complete when the next one is started. I just caught a case of three logchecks running in parallel, which is really what this locking is supposed to prevent. Turns out the locking is actually ineffective (see below), allowing multiple logcheck runs to run at the same time. Once the first one finishes, it kills its own lockfile-touch and removes the lockfile. I couldn't find any docs about how lockfile-touch behaves when its lockfile is deleted, but the source confirms that it exits with an error code. Due to this, when the second logcheck run completes, its lockfile-touch process will have quit, leading to the kill error message. Doing some tests shows that the cause of this problem are these lines [1]: lockfile-create --retry 1 "$LOCKFILE" > /dev/null 2>&1 if [ $? -eq 1 ]; then # Locked, error and quit This only treats an exit code of 1 as an error, while lockfile-create actually returns "4" in this case [2]. Changing this to `$? -ne 0`, or even more compact: if ! lockfile-create --retry 1 "$LOCKFILE" > /dev/null 2>&1; then will fix this problem. Gr.
