Re: V4.1.2: steadily increasing cpu load
As I reported, I upgraded twice from 3.2.3 to 4.1.2. After the first time I had that CPU load growing, after the last upgrade not. Since then, I have been doing a lot of testing and investigating because I wanted to know what exactly solved the problem. And the result: I don't know. I rolled back ev...

Re: V4.1.2: steadily increasing cpu load
Hi PoltoS, Your questions are difficult to answer. Perhaps you should take a look at the code? Preferably all 3 versions for comparison. I can put this together in a clearly arranged form. As for releasing buffers in the JS code versus letting the GC do it, I see a 20 Mb difference in memory (which ...

Re: ZWay crashed with SEGV + core dump
No, I still can't reproduce it.
You could get the idea that the two are connected. But I am sure that I already had the problem with the crashes before I developed the app I mentioned.

Re: V4.1.2: steadily increasing cpu load
Hey, someone ! ;) I actually wanted to wait a little longer and do some more tests before reporting my findings. But I'm convinced that I'm right. The comments about garbage collection in other thread led me in the right direction. I was able to find the app that generates the growth and isolate th...

Re: ZWay crashed with SEGV + core dump
I thought about whether the error pattern at that thread could also apply to me, but came to no conclusion: I'll try to share the solution with you. In short, the HTTP module (modhttp.so) is a wrapper of cURL for Google V8 JS engine Z-Way is using. The problem was that the thread releasing pointers ...

Re: ZWay crashed with SEGV + core dump
Any chance that the segmentation fault you have been seeing could be the same problem that was discussed in this thread? https://forum.z-wave.me/viewtopic.php?f=3419&t=35688 That particular issue was concerning incoming requests and was present in official releases until 4.0.3 IIRC. While the b...

Re: ZWay crashed with SEGV + core dump
I don't see any possibility of reproduction. The occurrence is completely unpredictable. One month it was 5 times, another time nothing in 4 months.
It's always the same: SEGV in v8 at the same address.

Re: ZWay crashed with SEGV + core dump
This happens from time to time, about 10 - 15 times per year. I just didn't know why until now. Only since the last two times have I known that it is a SEGV (after I moved to systemd). Normally it is not a big problem for me, because my watchdog restarts the server automatically. However, at the end...

Re: ZWay crashed with SEGV + core dump
It is 3.2.3.
Since this problem is existing since years over all Z-Way releases, I don't expect different behavior in the current release.
I will not upgrade to release 4 till the issue with growing CPU load is solved.

ZWay crashed with SEGV + core dump
Hi,
my z-way-server crashed this morning, a core dump was written.
As far as I can see, it was killed with SEGV in thread zway/core, libv8.so at 0x0000000076bef49c.
Perhaps it is possible to gain further insights from the attached collocation. If I can contribute further information, please ask.
