This seems like a server error to me. Undoubtedly a hassle to go back to a 6.0.1 server unless you've got an installation around somewhere, but the fact that it worked with 6.0.1, and then not with 6.0.2, and then when you went back with just 6.0.1 ZCO, it failed, sounds like a server issue.
It also sounds like ZCO needs to handle whatever this error is in a better way.
I need to come up with a way to repro this in-house. |
