3/18/2023 0 Comments Emby server unhandled exceptionOn a docker test environment, I was able to grep the ports used by Roon when you start it (no connection nor remote nor screen connected, just after starting the service). Same problem here with Roon Core installed on bare-metal machine with Ubuntu 18.04 LTS. Hope these Infos help to solve the issue.īecause currently it’s running but I don’t think that will be a “reliable” solution. Now I tried to put Emby “bridge mode” and couldn’t start it because I received a message that port 1900 (DLNA discovery) is in use. So it seems to be something network related. So, I stopped Emby and after a restart the Roon container (image: steefdebruijn)was up and running. I also tried a “native” installation with the same error.Īfter longer searching I stumbled about this thread. This usually indicatesĪ fatal error in the mono runtime or one of the native libraries What I saw was the following message in the Log: Got a SIGABRT while executing native code. I recreated my “Roon” Container with the same config I had before (also “host mode”) and couldn’t even connect to it with my android device because the server didn’t start. I’v a running Emby installation in “host mode”. I can remember that I had similar problems the last time I used Roon but “somehow” it worked.įirst of all I’m running OMV alongside with docker (docker-compose). It basically just calls the callback you method at the appropriate intervals.For a while I tried other Music-SW but renewed my License this morning and made a new installation. If the callback (running on an arbitrary thread) has an unhandled exception then you'll know about it. Callbacks have to be reentrant because the timer can fire before the last one finishes processing. Timers.Timer is also for server processing. The work is done on an arbitrary thread as well. Actually this version uses Threading.Timer internally to do the work. The only real difference is that this version raises an event when the timer elapses rather than calling a method. But your event handler can throw an exception. Since most events are not set up to handle exceptions the class wraps the entire call in a try-catch. The event handler must be reentrant as well. It relies on the standard WM_TIMER message for processing. Since it goes through the message queue it is not guaranteed accurate because the UI might be busy doing other things. However it does not need to be reentrant because the message queue is serialized. However the handler might get called outside the interval defined by the timer so the handler still has to do some time management. I don't use WinForms.Īs of v2 an unhandled exception in any thread will terminate the application. So if your service isn't terminating prematurely then it is being handled. If I run with an attached Visual Studio Debugger, the exception is thrown but not handled, certainly not by my own code. The service will not terminate but it seems like the thread in which the unhandled exception occurs is "destroyed" and cannot be called again. The service runs just fine apart from that. static internal void SynchronizeIDDSRepositoryWithRmxDB() Let's say the exception occurs at () because of a suddenly unavailable DB server. Then in the catch block is called with SqlCmd.Transaction being 'null'. A NullReferenceException is thrown but my UnhandledExceptionHandler is not called. Instead the service continues to run as if nothing happened but the thread which called this function will never work again. Other threads will continue to work apart from that. Timers are confusing so I'll try to summarize. There are at least 3 in the BCL: System.Timers, System.Threading and. Threading.Timer is for server processing although I have to say I don't know that I ever use it myself.
