Unfortunately yes - I had an issue last week with posting some data to an endpoint - all looked fine in dev of course, so I went to the prod logs and found that there was an issue with the logging. Turns out the logging was generating JSON using a library that didn't properly generate JSON if the output was multiple MB. Trying to replicate in dev then turned out to be a monumental pain because Java has not huge limits on static strings.
