This optional parameter allows you to define a custom SQL
query to reclaim an address whose lease has expired. If the ReclaimQuery
is an empty string, no reclaim query will be executed. Defaults
to
update RADPOOL set STATE=0 where STATE!=0 and EXPIRY < %0
%0
is replaced by the current time in Unix epoch seconds. By default reclaim
query runs immediately when AddressAllocator SQL module is loaded. You can
delay the start of reclaim check with DelayedPoolCheckTime. For more
information, see
Section 3.114.22. DelayedPoolCheckTime.
