Hi, has anyone encountered the problem of a not starting bitsquare on ubuntu although it was running before? I get this message in the log: … [JavaFX Application Thread] INFO i.b.c.u.Utilities: [os.name](http://os.name): Linux … [JavaFX Application Thread] INFO i.b.c.u.Utilities: os.version: 4.2.0-36-generic … [JavaFX Application Thread] INFO i.b.c.u.Utilities: os.arch: amd64 … [JavaFX Application Thread] INFO i.b.c.u.Utilities: sun.arch.data.model: 64 … [JavaFX Application Thread] INFO i.b.c.u.Utilities: JRE: 1.8.0\_112-b15 (Oracle Corporation) … [JavaFX Application Thread] INFO i.b.c.u.Utilities: JVM: 25.112-b15 (Java HotSpot™ 64-Bit Server VM) … [JavaFX Application Thread] INFO i.b.b.p.PriceFeedService: baseUrl for PriceFeedService: [http://h234zt7d2vztpwe.onion/](http://h234zt7d2vztpwe.onion/) … [JavaFX Application Thread] ERROR i.b.g.m.MainViewModel: initializeAllServices … [JavaFX Application Thread] ERROR i.b.p.n.TorNetworkNode: TorNode creation failed with exception: Could not create JavaWatchObserver Any suggestions?

Hm, never saw that before. Does it continue complaining after restart? ---

Unfortunatelly it does continue to fail. After 4 minutes the GUI suggests so restart. By having another look into the log file, I saw that this exception occured before, but in between it Bitsquare was starting perfectly and I even could do some trades. System and Bitsquare restarts won’t help. I also tried to restart the network manager “service network-manager restart” but other then that I’m out of ideas. ---

Just a quick update on this. I finally started bitsquare via console and it worked one time, so that I was able to transfer my bitcoins. After that it went back to the previously described problem. But I finally kind of solved the issue by running bitsquare as root, I usually don’t like to run software as root but for now I can work with that. Remember to move the appfolder to the root home directory… Hope this helps others! Regards!! ---

Thanks. Should be not needed to run as root. Maybe the control\_auth\_cookie file had issues? …/Bitsquare/mainnet/tor/.tor/control\_auth\_cookie You could try to remove all tor files inside the tor folder beside the files inside the hiddenservice folder. Do a backup before for safety. Could it be that you started Bitsquare once as root and later as user again? ---

Sorry, that I didn’t respond. I just tried your suggestion on my unix system and removed all files and folders besides the hiddenservice folder. Unfortunatelly, no luck. I startet to start bitsquare as root only after the mentioned issues. But, I am going to update to the later version, maybe the problem will resolve itself. Greetings! ---

I have the same error too. In my case, it’s because of the inotify limitation reached (I’m using Linux Mint). Try close other programs and restart bitsquare. ---

I doubt that this issue is connected to other opened programms, cause during my tests I had a freshly restarted system and just 2 terminal sessions as well as bitsquare running. ---

So I just updated bitsquare to the latest version on ubuntu, but unfortunatelly the problem still exists. The log shows the latest version: Feb-28 17:57:54.510 [JavaFX Application Thread] INFO i.b.app.Version: Version{ **VERSION=0.4.9.9** , P2P\_NETWORK\_VERSION=4, LOCAL\_DB\_VERSION=4, TRADE\_PROTOCOL\_VERSION=2, BTC\_NETWORK\_ID=0, getP2PNetworkId()=0} …with the same error message: Feb-28 17:58:06.738 [JavaFX Application Thread] ERROR i.b.p.n.TorNetworkNode: TorNode creation failed with exception: Could not create JavaWatchObserver As before, running with sudo still works. Any thoughts? Thanks in advance and regards ---

This error happen when I have Visual Studio Code open. If I close the VS Code, the application run normally. Your case might different though. ---

Seem that the inotify limit is too small on that user. can u increase that in the OS? ---

I think we are talking about two different issues here. Cause LinuxWatchService and JavaWatchObserver are not the same. I am going to re-setup my linux anyway and I am hoping to solve this. Might take so time, but I will keep you posted. Regards! ---
