The "maxPostSize" value is the maximum size in bytes of the POST that will be handled by the container FORM URL parameter parsing. Limit its size to reduce exposure to a denial-of-service attack. If "maxPostSize" is not set, the default value of 2097152 (2 MB) is used. ESX Agent Manager is configured in its shipping state to not set a value for "maxPostSize".
