Any hint/help how to proceed?

It looks like your linux box just shuts downs without warning and restarts
Have you checked the systems logs?

HI Vincent, thanks for the quick answer and hint to look at the syslog. Indeed I find entries that look like the Java VM crashes:

the hs_err_pid file is quite long and suggests that the Zulu Java vm has crashed. I did not find openHAB specific info in that file.

So - it looks like I should use a different java vm. Any suggestion as to which one I should use, and maybe a hint to installation instructions?

Many thanks
Stefan

Did you look at that file?

Yes I did. As I said, it suggest that the java vm crashed but did not show any openHAB specific info. I do see a couple of openHAB java threads but cannot detect any hint that suggests what the problem is:

@Kai
That one maybe for you,
Where would you like it raised?

Just as what the log says:

Jun 22 08:14:25 wi-openHAB karaf[20909]: # If you would like to submit a bug report, please visit:
Jun 22 08:14:25 wi-openHAB karaf[20909]: #   http://www.azulsystems.com/support/

A JVM crash is not a bug in the application, but in the JVM itself, so it should be reported to Azul - only they will know what kind of infos they would require to further analyse it.

@boxerfahrer This is obviously no quick solution for your issue, though. My best advice would be to try to disable add-ons one after the other and check whether it is caused by any of them. Also, you might want to try out the Oracle JDK as an alternative.

Thank you Kai. I have in the meantime installed the current Oracle JDK to see whether or not is it stable on my Odroid. The fact that the Zulu version I was using was not the most current one would probably send me into a loop with Azul Systems, and I wanted to avoid that.

I will report back on the stability of the current setup in a couple of days.

Thanks for your help Vincent and Kai - much appreciated
Stefan

So I am back, and a bit frustrated. I have tried the OpenJDK Versions 8u172 and 8u162 from Zulu as well as Oracle, plus Version 8u152 from Zulu. They all crash with OpenHAB and above listed setup.

Anyone else having trouble like this? Any advice?
It seems obvious that I have to go through the tedious process of uninstalling one binding after the other…

Best
Stefan

I did a complete re-installation of openHAB2.3
When I started the fresh installation (no itmes/rules/sitemaps added), the java vm crashed again.
The restart now hangs with the following lines in openhab.log

Jun 28, 2018 12:14:05 PM org.apache.karaf.main.lock.SimpleFileLock lock
INFO: Trying to lock /var/lib/openhab2/tmp/lock

INFO: Lock acquired. Setting startlevel to 100

Really frustrated…

Still trying … I did a clean install of the older Ubuntu 16.04 version and another clean install of OH2.3 - tried different jvm’s again. Same result - jvm crashed about 2-5 times a day.

I thought about the difference between my current setup and the last stable OH that I have been running stabel. That was OH2.2, but also with the older knx 1.X plugin instead of the most recent 2.X version. So I might have truble with the knx addon.

My question is - given that the current version is 2.X - how do I actually install the older 1.X version with OH2.3?

Thanks for your help
Stefan

What does the stack part of the hs_err_pid files look like? Perhaps it always shows the same native library some binding is using?

I have exactly the same problem (serveral reboots during a week, with more or less same java crash log file.
ODROID XU4
UBUNTU16.04
Openhab: v2.2, 2.3, 2.4
Plugins: sonos,weather1,mqtt1,tcp1,caldav1,caldav-command1,caldav-personal1
persistence: rrd4j
action:pushover

The only thing which is 100% sure:
it doesn’t happen with Openhab v2.2 (Snapshot 996), which is the last v2.1 version. I’m on this version for my productive system.

Another thing that is sure:
It is not depending on which java you use (oracle, zulu etc.)

And obviously it is not depending on the linux/Kernel version, as you have the same problem with UBUNTU18, which uses a 4.x kernel on the Odroid XU4. And as far as i can see, we use different bindings.

My personal feeling is, that the problem occur since the new Karaf version is used for Openhab. (if i remember correctly it was before the Openhab 2.2 was relaesed)

But one thing is very, very strange. Obviously we are the only one having this problem. And it seems, we are the only one using Odroid XU4.

If i have time, i will test the new obenhab version on an Odroid C2.

In my opinion the only change you have is to use v2.2_996 (if you want to stay on the ODROID XU4) and wait …???

Did you ever force Java to run on the big instead of the little cores?

Thank you Sigi and Wouter for your feedback and suggestions; rellay appreciated.

I haven’t tried the OH2.2_996 or CPU affinity yet because … since going back to the knx V1 addon I have not had any crashes. Seems odd, but it was also the only openHAB related change I introduced when going from my old Odroid U3 to the XU4. I mainly did this because Ubuntu 14.04 was the last official linux version supported on the U3.

Well, since I haven’t seen any other knx V2 related complains this might indeed be a platform specific problem. Strange thing though.

I am stil running an outdate Ubuntu 16.04 version, so I will go back to the 18.04 version and try with knx V1. If that runs stable for me, it is worth more to me than knx V2. I will be back to report on this

Thanks!
Stefan

Good morning,

I re-installed Ubuntu 18.04 on my XU4 last night, and then OH2.3 with knx V1.12.0
All stable so far.

I will report back in a couple of days

Stefan

Great! It could be that the old binding uses more resources so the Java process never goes to the little cores. :wink:

When there are native issues with the KNX2 binding on your ODROID XU4 you will probably always see KNX packages in the stack of the hs_err_pid file. See my previous comment.

Can you post the stack from one of the crashes of the hs_err_pid files?

There’s also a thread about openHAB crashing on the ODROID forums where pinning the process to the big cores seems to have resolved the crashing.

Well I did not have to wait too long for the next crash…
OH 2.3 with knx V1.12.0

This is what the syslog sais:
