Hi @lmajano, thanks for the response. I've updated to 6.7... it'll be some time before I can tell whether I'm getting the same issues - but a new problem seems to be cropping up now, in the

objectMarshaller.cfc

at line 70: The parameter 1 of function ToBinary, which is now xxxx must be a base-64 encoded string. I'm trying to set up a test case, but this looks to be a similar scenario whereby the error only happens occasionally and the majority of calls are successful.
