Upload properly formatted payload files for Large Merchant Services (LMS) jobs
LMS jobs would hang or take too long if the uploaded payload file contained the requests on very few lines. Such jobs also negatively impacted the execution times of other jobs that were being processed.
In order to avoid this situation, the LMS team has implemented a feature to proactively detect and reject payload files that do not have line breaks (>20000 chars on a single line). This feature will be turned on in production during the week of 4th of April 2011.
Call for action: Please ensure that you incorporate line breaks between requests to avoid this situation. Also make sure that individual requests are properly formatted and are not on a single line.
