After upgrading to Spectrum 10.4.2, SPM tests are recreated after every poll causing all SPM tests to fail.
Code changes in 10.4.2 caused this bug.
Release : 20.2
Component : Spectrum Core / SpectroSERVER
The fix for the DE481503 was already delivered in the DX NetOps Spectrum 10.4.3 / 20.2.7 GA release.
The fix will be available in the next upcoming Spectrum 21.2 release too.
