[Unbound-users] Old entries in the requestlist

I'm running unbound-1.4.3 on a pair of busy Linux caches. It has been
compiled with libevent.
The request list is slowly filling up. I've tried various sizes (it's
currently 4 threads with 4096 requests/thread, so 16384 in total), and
the request list always fills up (and starts discarding incoming
queries). unbound-control dump_requestlist shows entries that are
hours old, eg
175 A IN 1.10076.0.0.276.0.47.b.radar.cedexis.net. 2047.857478
iterator wants AAAA IN flip1.cedexis.net. AAAA IN flip2.cedexis.net.
311 A IN medias.lemonde.fr. 2104.565184 iterator wants AAAA IN
flip1.cedexis.net. AAAA IN flip2.cedexis.net.
294 A IN intra05.griffin-net.com. 12574.009854 iterator wait for (empty_list)
316 A IN L221SR07.griffin-net.com. 12811.485119 iterator wait for
Has anyone else seen this? Why aren't they being discarded when they
reach a certain age?
I've not tried a more recent version of Unbound, but I didn't see
anything in the release notes to suggest this issue is fixed. I was
running 1.4.3 on Solaris 10 before without noting this problem.
