> Key: KARAF-2552
> URL: https://issues.apache.org/jira/browse/KARAF-2552
> Project: Karaf
> Issue Type: Bug
> Components: karaf-shell
> Affects Versions: 2.3.3
> Environment: Mac OS X on java version "1.7.0_45" and java version
> "1.6.0_65"
> Windows 7 on java version "1.6.0_41"
> Reporter: Mateo Ramey
> Assignee: Freeman Fang
> Priority: Critical
> Fix For: 2.4.0, 3.0.0, 2.3.4
>
>
> Running log:tail on the admin console causes 100% cpu usage. There were no
> logs being shown during the tail, just simply running the tail is causing the
> CPU to spike up.
> Steps to reproduce:
> 1) Download Karaf 2.3.3 distribution.
> 2) Start karaf
> 3) run log:tail command
> 4) Watch CPU monitor (top in *nix or task manager in windows) show full cpu
> usage
> 5) ctrl-c out of log:tail and CPU usage goes back to idle.
> Attaching a profiler to Karaf identified the method taking up CPU as:
> org.apache.karaf.shell.console.jline.DelayedStarted.run()
> Not sure if that is fully accurate, but might be a place to start.
> Note: Was unable to reproduce issue on Karaf 2.3.2 and as a result we have
> had to revert back to that version.
> Let me know if you have any additional questions.
> Thanks!
