SETting a id of an active poller will cause all the rows of this poller in the rlEventsTable to be destroyed. This is equivalent to SETting rlEventsStatus of each row of this poller to 'destroy'. GET operation on this variable is meaningless, and the value 0 will be returned in this case (actual pollers start from 1).
