QUIET_MAX_WAIT <seconds>
When ctQUIET() is unable to block internal activity due to some long running action, it will eventually give up and fail with error 843 after a fixed number of internal attempts. During this interval, all new database activity is blocked. This keyword allows controlling this server wide limit with an additional time based limit. This wait begins AFTER any transaction timeout specified by the ctQUIET() API call.
Default = 60 seconds. (Minimum = 5 seconds).
