Hello,

do you get also dialog statistics? tm stats are not relevant in this context.

Cheers,
Daniel

Hi, Daniel

No, the dialogs were not terminated after 10 minutes if no BYE message was sent.

Not using ims_dialog, but it may be that it doesn't send bye when the dialog lifetime elapses, just destroys the structure it keeps in memory. With the other dialog module, there is a parameter to set if you want BYE to be sent.

But if Default value(43200) was set,  the S-CSCF will run out of memory finally (after 200000 calls).

Were all these calls still active?

Hi,
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

 

 

Have any relation with this parameter and memory release ?

Yes, the structure kept for each call is destroyed after lifetime. But it should be also destroyed if the BYE is received.

Cheers,
Daniel

Any impacts if using value 600 at production environment ?

Thanks.

Hello,

that should be the call lifetime. Are the dialogs terminated after 10 minutes?

Cheers,
Daniel

Dear all,

What's the meaning of ims_dialog  default_timeout parameter ?
Default value is 「43200 (12 hours)」

When modparam("ims_dialog", "default_timeout", 600) was set,

the situation of Kamailio S-CSCF out of memory was solved and is running smoothly.

Debian 8 with Kamailio 4.4.7
