Security context stack is growing large

[tcoufal]

Hi Guys,

I have quite large problem. It is few days ago when this warning start to showing up in my Application log. It is very fast filling my Application log files.

I can see that the problem is coming from WebSocket subsystem, but I cannot find from where exactly.

We are using Kepserver + IoT gateway with Websocket agents.

But it worked without problems few months until know.

Is there anyway how to trace the source?

Thanks

Tomas

Do you have a connections server? Is there any other errors in the application log? What is your thingworx version?

[tcoufal]

We are not using a connection server. Version is 7.2.0.

There is only one (two) other errors in AppLog

Are the errors messages consistent with the warning messages? From the error message it seems that service is being invoked with some null data.

[tcoufal]

No consistency that I can find.

I would need to know what that Message is in a first place.

What does it mean?

This is the error which I think is of some importance, however I dont where the problem could be.

error executing APIRequest Message: Unable to dispatch [ uri = /Things/CBF6/Services/UpdateSubscribedPropertyValues/]: Unable to Invoke Service UpdateSubscribedPropertyValues on CBF6 : null, sending ERROR ResponseMessage to caller!

Found the problem.

I was heaving few subscriptions of DataChangeEvent and one was set on Property that I was changing in the same script. So it was stuck in a loop.

Stupid..

Luckily I was not the one who made that mistake , but it was more difficult to find.

Hi,

With a fresh install of TWX Postgre 7.4 (after running script DBCleanup, DBSetup, SchemaSetup), I imported some extension like Mail, Autocomplete, Logout Button.... Then, with user Administrator, create and delete Things (GenericThing) generate these warnings !

Hi Tomas,

We have a condition to terminate loop, so it should execute right, but why still it give that error?
