Hi,
while uploading a process (with extended tasks) via the rest api, sometimes (when process is a bit longer than usual) i get this error:

any idea on how to avoid it?

Seems like an exception occurs and the "message" of the exception contains CRLF-character. Do you see any exception prior to that in your log? Although very rare, this is an issue that needs to be addressed in the next version of activiti… I'll take care of that.
