amazonechocontrol blocks thingHandler threads after some days of uptime

[NulPex]

After some uptime the openhab thinghandler threads get blocked. I have four blocked threads in my thread dump at these points:

• at org.smarthomej.binding.amazonechocontrol.internal.handler.AccountHandler.checkLogin(AccountHandler.java:377)
• at org.smarthomej.binding.amazonechocontrol.internal.handler.AccountHandler.updateSmartHomeState(AccountHandler.java:907)
• at org.smarthomej.binding.amazonechocontrol.internal.handler.AccountHandler.updateSmartHomeState(AccountHandler.java:907)
• at org.openhab.core.thing.binding.BaseThingHandler.updateStatus(BaseThingHandler.java:376)

This causes all things to be not updated anymore and requires an openhab restart. Does checkLogin not come back in my case?

Which binding version and which openHAB version? line 907 in ÀccountHandler` is just a logger in current 4.0 code, that can't block.

Hi Jan, thanks for answering. It's running on 3.2.16 │ SmartHome/J Add-ons :: Bundles :: Amazon Echo Control Binding 3.2.16 │ SmartHome/J Add-ons :: Bundles :: Common Components

and OH 3.4.4

The logger call in line 907 is the first statement in the synchronized method, i believe this is how it's displayed when the thread can't enter the method. But I might be wrong. Any suggestions, test or version updates i could try?

Is there any exception in the log? I have the feeling that maybe something goes wrong in the "last" (=fifth) thread and that does not properly exit the method which then blocks.

There is an openhab cloud reconnect happening at this time. But no further exceptions.

Ok, that seems to indicate that there is a general network connectivity issue at that time. I'll see if I can reproduce that.
