EventAdmin keeps timing out

Hello, I keep getting this msg in the logfiles when openhab freezes. and none of my items work.

2018-01-02 22:35:53.952 [WARN ] [org.apache.karaf.services.eventadmin] - EventAdmin: Blacklisting ServiceReference [{org.osgi.service.event.EventHandler, org.eclipse.smarthome.core.events.EventPublisher}={event.topics=smarthome, component.name=org.eclipse.smarthome.core.internal.events.OSGiEventManager, component.id=77, service.id=170, service.bundleid=110, service.scope=bundle} | Bundle(org.eclipse.smarthome.core_0.10.0.201712141004 [110])] due to timeout!

I saw a other post mentioning it. But the solution did not help.

the only way i can recover from this is a reboot. it happens around 1 time every 24 hours

Last one was within 5 hours of the one before that

Is there a solution to this problem?
