The problem here is that ActivityCoordinatorImpl is trying to
keep track of recovery unit identifiers, and incorrectly
allocates entries in a table under HLSInformation, but then
removes them (which does not cause any errors to be seen) from
a table held by the recovery log service. This leaves the
entries in the table under HLSInformation.
Problem conclusion
Classes ActivityCoordinatorImpl, UserActivityImpl and
HLSInformation have been changed to ensure that only 1 table is
manipulated by the ActivityCoordinatorImpl.
The fix for this APAR is currently targeted for inclusion in
fixpack 5.1.1.9.
