Hello,
there are a lot of active dialogs there, however, as they BYEs are replied, the structures should be released in short time and shared memory freed. Do you execute dlg_manage() when receiving BYE?
Cheers, Daniel

Hello, do you get also dialog statistics? tm stats are not relevant in this context. Cheers, DanielHi,
I'm re-running SIPp. The share memory is decreaing and will run out of memory. Is below information enough ?

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 = 415668000Have 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, DanielAny impacts if using value 600 at production environment ?
