Since Qlikview April 2019 SR2 QVD files are getting corruped on the server sometimes. When reloading a QVW using such a QVD results in Error: Unsupported or bad format in QVD file. QVW files are also getting corrupted. Downgrading to SR1 resolved the problem. I have just tested SR3 which is giving the same errors. Downgraded to SR1 again.
