[SOLVED] Openhab 2.3 running problems

[eXadra (Pedro)]

Hello all,
I have a Openhab 2.3 version running in a Debian 8 platform.
Until 2 months ago I had my Openhab 1.8.3 running smooth and decided to upgrade to 2.3, everithing went well with just a few bumps that where solved.
The issue that I bring is that the Openhab ramdomly (can take one day… one week …) stops the normal work; it still opens thru the web acess or the habdroid but the switches when acted dont change the icon state, graphics are not displayed and seems to me that rules are not activated.
Cheking the logs (openhab.log) all are ok without errors and if I try to restart the service (service openhab2 restart) it stays forever waiting.
Can someone help, this installation is controlling all my house and farm and when is hangs it gives me BIG problems.

Thanks in advance

It looks like you are running out of threads. “rules are not activated”
Have a look at this:

(OH 1.x and OH 2.x Rules DSL only] Why have my Rules stopped running? Why Thread::sleep is a bad idea

EDIT: While the general advice in this article still applies (i.e. it’s always worth while to make short running rules), the problem described in this article only applies to OH 1.x and Rules DSL in OH 2.x. In OH 3 and beyond, this is no longer a problem so if your rules stop running in any version of OH released in the last two years (as of this edit in 1/2023) this is not your problem. By way of explanation, in OH 3 each rule gets it’s own thread. It is no longer possible for a rule to starve…

Do you have any rules with Thread::sleep?
Or any while loop? Or any long running actions like executeCommandLine/httpGetRequest?

Aftres some time having randomly this problem I reinstalled the Debian (upgraded it to 9) and installed all the other packages including OPENHAB and the problem until now didnt appeared yet.
