Hi,
did you wait the default 12 hours (default_timeout) for the dialog to be
released? If after that time, the dialog is still there, it is probably
because of a bug.
You should also take into account the matching mode currently configured:
http://www.kamailio.org/docs/modules/3.3.x/modules_k/dialog.html#idp129680.
The default behavior is to add a dialog-id cookie in the route header but
if your user agent fails to add the parameter when it sends the subsequent
requests, the dialog will not be properly tracked and you could end with a
bunch of active "unfinished" dialogs in memory.
Regards,

Hello,****

Another dialog got stuck in kamailio, so I checked a few kamctl commands.
This is what I found.****
** **
When viewing the profile size the count is 0 (using kamctl fifo
profile_get_size [NAME])****
When using the kamctl fifo get_statistics all command, the
dialog:active_dialogs shows 1. There are no other calls active at this
point, so this must be the one that got stuck. ****
** **
The call is still in state 4. I don’t know what this means, but I’m
guessing active.****

Why did the dialog module fail to release this dialog? The profile was
configured to allow 2 concurrent calls. We called the number using two
phones and only one made it through.****
** **
Is this a bug?****

Hello,****
** **
Using the dialog module. According to the documentation a dialog is
automatically destroyed when a BYE is received. In case of no BYE, the
dialog lifetime is controlled via the default timeout. ****
** **
I’m assuming the dialog module only creates a dialog when a 200 OK is
received on the INVITE. So if a CANCEL request is sent for this INVITE or
the server answers with anything but a 200 OK, no dialog is created and
maintained by the dialog module?****
** **
Also, when the dialog is terminated, is it guaranteed the dialog entry is
removed from memory at all times, but there might be a chance the dialog
remains stored in the database table because of some error? I’m using the
dialog module to control the number of calls allowed to a certain
destination, but it sometimes does occur that an entry in the database is
not removed, but I’m not sure if the dialog is also removed from memory
when this happens. ****
** **
I hope someone could clear this out for me.****
** **
Thanks,****
