Hi , my guess is too that it is the second call.
In case we want to go for a loop, should we have a maximum number of retry operations like 10 or 100 ?
Another option might be to always make the buffer a little bigger (how much can be discussed)  and use the larger buffer to account  for some increase in the number of processes.
