|
The current number of times that the balloon driver

has attempted to increase the size of the balloon.
|
|
|
|
|
The default value is one. With max_retry_count being
|
|
|
|
|
zero (unlimited), this means that the driver will attempt
|
|
|
|
|
to retry with a 'schedule_delay' delay.

'max_schedule_delay' is reached at which point it
