I had some serious problems with unexpected OH restarts today (sometimes maybe an estimated 5 times per hour) and could not really find out what was causing this…
However I realised that my PSA bridge was offline and I saw some errors (nothing really out of the ordinary, just some authentication issues) in the logs. Since I’m hardly using it I just disabled the bridge and no restart occurred so far 
Could this be related?
LOL - a minute after I wrote this OH just restarted again 
never mind…
