Hi Raymond,

try this in failure route:

failure_route[x] {
    log(1,"--inside failure route\n");
    if (t_check_status("(404)|(487)")) {
          log(1,"--status is 404 or 487\n");
          avp_db_delete("$from","s:/inuse"); # no need to load before

watch the log messages and the mysql queries in the logs.
