Thingworx Integration Runtime timed out exceptions

[PreetiGupta]

We are in process of upgrading our Thingworx platform to 9.3.3

We are using integration-runtime-8.0.13-b1669 Integration runtime. We are seeing below api timed out issue intermittently.  We are actively working with PTC on this issue (C16735337) however, the issue is sporadic in nature so we are not able narrow down what is the issue here. The client processor thread is not receving 200 response back from Windchill on the web request intermittently.

We have been very stable on our 8.x enviroments in production for last 5 years. Wondering if other customers have faced similar issues upgrading to 9.3.

Hi @PreetiGupta.

Is there some reason you need to be on 9.3.3?  There was a bug in that release due to a 30 minute timer that was set for testing, that was causing the installer to fail and ThingWorx to take 30 minutes to start up.  I don't know if it would be affecting the functionality you are using, but if there is no driving reason to stay on 9.3.3, you might try upgrading to a higher patch level.  The latest one if 9.3.8.

Regards.
