I'm trying to reload a hash table but receiving an error: 
error: 500 - Mtree reload failed



[root@kamailio]# /usr/local/sbin/kamcmd htable.listTables
{
    name: auth
    dbtable:
    dbmode: 0
    expire: 0
    updateexpire: 1
    size: 256
     dmqreplicate: 0
}

[root@kamailio]# /usr/local/sbin/kamcmd htable.dump auth
{
    entry: 69
    size: 1
    slot: {
    {
         name: username::8.8.8.8
         value: 0
         type: int
     }
  }
}

[root@kamailio]# /usr/local/sbin/kamcmd htable.reload auth
error: 500 - Mtree reload failed
