supervisor_max_postboard_retry = retries
Retries is the total number of attempts the Supervisor will make before giving up on communicating to "post" clients before giving up.
A "post"-style callback is set up for client programs (such as a GUI or a script) to "subscribe" to events. This requires that the client is listening on a port, and that the client acknowledge the receipt of events, which is where post comes in. Examples of use include the "waiton" option of qbsub, which uses the qbwaitfor() API call. qbsubmitpost() also submits a "post" callback.
