Hello Folks, I found the root cause of this issue. In file ms_msg_list.c, issue is on line 290. (https://github.com/sipwise/kamailio/blob/master/modules/msilo/ms_msg_list.c) Line 290: p0 = p0->next; should be like this below : p0 = ml->lsent; The issue is p0->next becomes null in first iteration so it won't process more than one element in 'while' loop. Hence this is the main cause of slowness of message deletion. I have tested modified code and it works fine now. Develoerps, Please review this change and advise accordingly.

My issue is cleanup of stored message is taking very long time specially when many messages are left for target users. After further investigation I realized, only one message gets deleted in one pass and next in next pass ( after 30 second default timer). Is it intentional ? How can we make sure that all delivered messages get deleted right away for that user?
