[jsscripting] After some time ALL ECMA2021 JavaScript scripts are not working anymore

[Sascha-L]

openHAB 3.3.0 M1
Windows 10 Pro x64

All of my ECMA2021 JS scripts are working fine, without any erros. After some days none of them are working anymore, because openHAB throws exceptions for any keyword, namespace, etc.

Example:

2022-04-02 11:53:20.728 [ERROR] [b.automation.script.javascript.stack] - Failed to execute script:

It seems that the whole environment/runtime to execute those ECMA2021 JS scripts is crashed and not working anymore. The more often ECMA2021 JS scripts are executed, the earlier this issue happens.

Maybe @digitaldan or @jpg0 has an idea why it crashes?

This sounds like a memory leak, my guess is there is OOM error earlier in the logs somewhere. Its possible this is related to #12577 or possibly openhab/openhab-core#2897 which was just fixed a few days ago in the core.

Hi,

directly after I read your comment that there was just commited a fix, I installed the Snapshot (Build #2857) version. Since then it is running and running and running without any issues anymore! Great! :-) Also the WebUI is very fast now. Until Milestone 2 the WebUI was getting slower and slower day after day - maybe due to the memory leakage.

So the issue seems to be fixed! :-)
