Miele Cloud Binding on OpenHab Docker cannot authorize due to too many threads required

These parameters were not in the conf/services/runtime.cfg so I had to copy them in.

After restartting the container they say what you showed:

openhab> config:list "(service.pid=org.openhab.webclient)"
----------------------------------------------------------------
Pid:            org.openhab.webclient
BundleLocation: null
Properties:
   maxThreadsCustom = 40
   maxThreadsShared = 80
   minThreadsCustom = 20
   minThreadsShared = 20
   service.pid = org.openhab.webclient

I tried the pairing again and it worked.

This issue has been mentioned on openHAB Community. There might be relevant details there:

You can fix this by reconfiguring the parameters in conf/services/runtime.cfg:

openhab-distro/distributions/openhab/src/main/resources/conf/services/runtime.cfg

Lines 278 to 286 in 678720a

	################################## WEBCLIENT ###################################
	# For installations on higher end systems with many cores, increasing number of webclient threads
	# may be necessary. Usually, this is reported with "Insufficient configured threads" in the logs.
	#
	# org.openhab.webclient:minThreadsShared = 20
	# org.openhab.webclient:maxThreadsShared = 80
	# org.openhab.webclient:minThreadsCustom = 20
	# org.openhab.webclient:maxThreadsCustom = 40

I changed both conf/services/runtime.cfg and dist/conf/services/runtime.cfg.

I then restarted the container. Tried the mielecloud authentication and had the same error.

The conf/services/runtime.cfg still shows the org.openhab.webclient:maxThreadsCustom = 80 but the dist/conf/services/runtime.cfg was overwritten due to restarting the container as this part is not persisted.

You'll only need to update conf/services/runtime.cfg

Did you also uncomment the lines by removing the # ?

After uncommenting the lines you can check that the values have been applied on the console:

openhab> config:list "(service.pid=org.openhab.webclient)"                                                                                                                                                                             
----------------------------------------------------------------
Pid:            org.openhab.webclient
BundleLocation: null
Properties:
   maxThreadsCustom = 40
   maxThreadsShared = 80
   minThreadsCustom = 20
   minThreadsShared = 20
   service.pid = org.openhab.webclient

Can this configuration be automated for a deployment on a system with many cores, like mine? I have been struggling for more than half a year with this, so now I might be the only one but in the future there might be more.

Insufficient configured threads: required=16 < max=10 for QueuedThreadPool[OH-httpClient-OAuthConnector]

Maybe we can use similar logic as Jetty to automatically determine the lower bounds of these values. That way users do not need to reconfigure the values on computers with a lot of cores.
