Moved to an USB-SSD, system still crashing. I guess it has to do with some of my rules where I try to process numeric values coming from MQTT. But even if I have some error in my rules, the system should not freeze/crash that way.
Use the ESHD http://docs.openhab.org/installation/designer.html to check if you have any errors in your items, rules, …
Hi Robert,
i´m pretty sure its not related to errors in an rule or item that the system crashes the way your and my system do.
Since i´ve change the SD…no freeze so far. I´ve set up another system from scratch to test the “old” SD Card.
@Thorhammer, then we have two different issues. I commented the suspected rule out - and my system runs stable for 18 hours now.
@sihui, I do use the ESHD but it shows me a lot of errors where are none. So, the highlighting feature is a kind of useless - at least for me.
I will now reacitvate everything step by step and watch, when the system starts to crash.
It catches a lot of the basic stuff. If you are an experienced programmer, you are right, they don’t make typos. 
. Is it only one rule or the hole rule file? Could you paste the rule here?Any news? Since 2.1 openhab2 freezes every few days.
I’m starting to experience Openhab crashing. It started last Thursday. Today it crashed in the morning and in the afternoon. Any suggestions on how to debug this issue?
