Single WebDispatchers: A Request for server was sent & was sent to server &.

Hi Everyone,

We are experiencing the issue of an intermittent 500 SAP Internal Server Error that sometimes appear at random times when accessing the webdynpro web service, this error can appear on all pages without exception, as follows :

We have tried to check the related SAP Note, there is no indication of a parameter error in the load balancer, while in the ICM trace there is also no log indicating the above error, and several other solutions have been tried but we have not been successful.

Currently we have upgraded our webdispatcher too from 7.53 patch 22 to 7.53 patch 1111 (latest,end of 2022 release)Has anyone else encountered and resolved this issue?

Any advice would be very appreciated.Thanks!
