[SR-Users] Problem with update/retrigger a htable

Hi members, I run into a problemm with htable. For user push notifications I need a loop. So I did the following for a first test: modparam("htable", "htable", "user=>size=3;autoexpire=5") ... event_route[htable:mod-init] {     xinfo("htable init");     $sht(user=>testkey) = "testvalue"; } event_route[htable:expired:user] {     xinfo("Record expired $shtrecord(key) => $shtrecord(value)");     $sht(user=>$shtrecord(key)) = $shtrecord(value); } I see the htable init, and I reach Record expired, but only once. The 'new' entry $sht(user=>$shtrecord(key)) = $shtrecord(value); seams not to be re-added, because I never reach the expired event again. I expected to see cyclic expired events. Also strange: expire is set to 5 seconds I get: Nov 21 08:34:50 xxx /usr/sbin/kamailio[254662]: INFO: <script>: htable init ... Nov 21 08:35:10 xxx /usr/sbin/kamailio[254671]: INFO: <script>: Record expired testkey => testvalue If I'm right, this are 20 seconds and not 5. Any ideas what's wrong? Best regards
