The problem was first seen on 10.1.2 with CABI 4.1 SP3and resolved with patch Spectrum_10.01.02.PTF_10.1.208.
The patch release note also contains instruction of additional steps that need to be run on the CABI server.
The patch was added to 10.2 but as the version of CABI has not changed since 10.1.2, so the cause of the problem still remains in CABI.
As a result, the steps from the release notes, still need to be run on Spectrum 10.2 and higher when integrated with CABI 4.1 SP3
