Re: Karaf freezes up under MS-Windows

Based on the latest Apache Karaf v4.1.7, run it on Windows 7.

Still freeze up at Windows side after entering the command "list - t 0"
but the same symptom never happen at Linux side.

So the bug is really related to MS-Windows.

May you file this symptom as a bug.

Best Rgds,

Tom Leung

RE: Karaf freezes up under MS-Windows

Posted by "Leschke, Scott" <SL...@medline.com>.
When 4.2.2 comes out, I'm should be able to run Karaf as a service under jdk 10+.  At that point, I'll be able to check if the same situation exists when running log:tail in the Karaf client connected to the service.  I'm thinking it probably won't.

Thanks for the update Scott.

RE: Karaf freezes up under MS-Windows

Posted by "Leschke, Scott" <SL...@medline.com>.
I've hesitated to say anything since I wasn't real sure how to verify but I've seen related behavior with 4.2.1 on Windows Server 2016.

What I see happen is that if I run Karaf in a console, which I think is key, and I do a log:tail,  at some point the display stops updating.  Things start working if I hit enter or CTRL-C in the window.

I have a warning message in my main control thread that if my thread runs long (which it should never do).  When I hit a key in the console, I see the message indicating that it's not waking up from a timed sleep cycle.  The thread has a 20 sec. polling cycle and does very little so it generally runs in a 100 or 200 hundred millis maybe.

The control thread has a priority default+1 so it is the highest priority thread in the app.  I have 4.2.0 that I run as a service on a couple of other machines and I've never seen this issue so I'm reasonably sure that the issue is related to running in a console window.
