You might know what’s in Karaf, but I don’t. What are the versions of config
admin and DS that you are using?
Since you say this is occurring in production it might not be possible, but if
you can get a log with debug trace on (setting ds.loglevel=debug) with the
trunk version of DS that would be extremely helpful figuring out what is going
on…. I added some logging of the config change count since the last release.
thanks
