ATP UI shows internal error with the Synapse when enabling correlation with the SEPM DB. When un-checking the Synapse correlation, after a few seconds the screen refreshes. The box still shows checked with the internal error. (Note: See Error Message section.)
Most likely there is possibility of ATP making parallel calls to eLCP manager to update its configuration leading to collector.xml file corruption since eLCP manager is not thread safe
TSE should contact the PSE in order to fix the content.xml if solution given in TECH239984 doesn't work.
