Event bit stays set and loops

A task waits with xEventGroupWaitBits(eg, BIT_RX, pdFALSE, pdTRUE, portMAX_DELAY) in a loop. After the first event it spins forever without blocking. Why?

A.portMAX_DELAY makes the wait return at once instead of blockingB.Waiting for all bits is not allowed when only one bit is givenC.xClearOnExit is pdFALSE, so the bit stays set and each wait returnsD.An event group can only be waited on once by each task
