Hi Pravin,
This exception indicates that current requestor is waiting for resources which are held by thread id WebContainer : 0.
You need to check in entire PegaRULES log for WebContainer : 0 to see what this is doing.

Hi Pravin,
This exception indicates that current requestor is waiting for resources which are held by thread id WebContainer : 0.
You need to check in entire PegaRULES log for WebContainer : 0 to see what this is doing.
Interesting occurrence would be one with status as running /running in native.
Review stake trace and you should be able to find root cause on why WebContainer : 0 thread is busy.

Do any of the actions in your submission takes long time? Like service calls, db calls, large reporting data retrieval?
Not sure if you referred to below article. The solution in below article is providing steps to increase the requestor timeout which resolves the issue.
