Package: xymon-client
Version: 4.3.17-6+deb8u1
Severity: normal
Tags: upstream
Dear Maintainer,
* What exactly did you do (or not do) that was effective (or
ineffective)?
When installing xymon-client on a system that serves as a host for running LXC
containers, it happens, that
starting the xymon-client on the host becomes impossible when a xymon-client is
running in one of the containers.
The initscript claims that the xymon-client is already running. This message is
- inside the script - generated by
the start-stop-daemon invocation. Stopping the daemon might also be affected.
* What outcome did you expect instead?
The expected bahaviour would be that the client starts normally, despite the
clients already running inside the
containers.
* Have you identified a reason for that outcome?
It seems that start-stop-daemon is invoked in a way that makes it only match
the processes executable name for
detecting if the daemon needs to be started/stopped. That is not enough when
multiple instances of a process
might be running on the same system but in multiple process namespaces.
* How can the problem be fixed?
The problem can be fixed by adding the --pidfile "$PIDFILE" argument to
start-stop-daemon. It is already in the
commandline, but only as an argument to the xymon-client. A patch is (to be)
attached.
There is an init script in the upstream sources debian/ directory
(debian/xymon.init) that also has the problem.
I am uncertain, if the problem is to be fixed there.
