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

Hi,
I'm re-running SIPp.
The share memory is decreaing and will run out of memory.
Is below information enough ?

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

2xx: 978329

}
# 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,

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
