Resolution

Sometimes the gateway may fail to create the -bigmsg directory that it uses as a cache for large requests. In these cases, creating a -bigmsg directory in the temp directory indicated in the error message will resolve the problem.

For further information about how the API Gateway caches large messages, please refer to the section in the Administrator's Guide on the spilltodisk setting.
