In SIPp, the calls were finishes.
But in Kamailio, the calls seem keep in the memory and run out of memory.
Can any parameter solve this problem?
Is it  a solution  to set "ims_dialog", "default_timeout" to  600 ?

# kamcmd tm.stats
{
        current: 69
        waiting: 0
        total: 991300
        total_local: 0
        rpl_received: 2183891
        rpl_generated: 20232
        rpl_sent: 1475856
        6xx: 0
        5xx: 2704
        4xx: 10124
        3xx: 0
        2xx: 978329
        created: 991300
        freed: 991231
        delayed_free: 0
}
# kamctl stats shmem
shmem:fragments = 1630
shmem:free_size = 4303040
shmem:max_used_size = 536870912
shmem:real_used_size = 532567872
shmem:total_size = 536870912
shmem:used_size = 415668000
