Hi guys, I was torn between posting to users or dev, but I am pretty sure both my observations are caused by some kind of race condition or bug, rather than my misuse (still a possibility :-))
Problem 1) data/log/karaf.log contains every log message twice when i watch the log file on disk, all lines are duplicated, when I log into karaf via client.sh and I do a log:display, I see the exact same lines, but only once. I have not yet been able to reproduce the problem willingly. however it happens relatively frequently on my installations(about 30% i would say). My closest guess is that somehow the logging subsystem reloads and leaves appenders alive. Could this be related to using "private static final LOGGER" ? Problem 2) sometimes karaf does not start at all, but hangs after some seemingly duplicate locking messages This seems like a race condition to me: Aug 11, 2015 9:47:59 AM org.apache.karaf.main.Main launch INFO: Installing and starting initial bundles Aug 11, 2015 9:48:00 AM org.apache.karaf.main.Main launch INFO: All initial bundles installed and set to start Aug 11, 2015 9:48:00 AM org.apache.karaf.main.lock.SimpleFileLock lock INFO: Trying to lock /opt/karaf/lock Aug 11, 2015 9:48:00 AM org.apache.karaf.main.lock.SimpleFileLock lock INFO: Lock acquired Aug 11, 2015 9:48:00 AM org.apache.karaf.main.Main$KarafLockCallback lockAquired INFO: Lock acquired.

Setting startlevel to 100 I can open Jira issues if you think i found something here, but unfortunately I have no idea how to troubleshoot it further, if you have thoughts, please let me know. I am willing to experiment. Fabian
