[SR-Users] dialog:active_dialogs counter is steadily increasing

[Andrew Pogrebennyk]

Hi,
using kamailio 4.4.5, we have noticed that the active_dialogs counter is
not accurate and there seems to be some kind of "leak" present at least
on higher loaded systems.

For example, here active_dialogs was reporting just a bit over 1000
dialogs, but the numbers of dialogs confirmed and not just do not sum up
together to that value:

# grep -c 'state:: 1' dialogs_20170919_1712.txt
5
# grep -c 'state:: 2' dialogs_20170919_1712.txt
62
# grep -c 'state:: 3' dialogs_20170919_1712.txt
0
# grep -c 'state:: 4' dialogs_20170919_1712.txt
531
# grep -c 'state:: 5' dialogs_20170919_1712.txt
27

What could be the possible reasons or issues that lead to that?

We are thinking now about switching statistics collection to:
kamctl fifo dlg_list | grep -c 'state:: 4'
or reading the count directly from the database, as it seems to only
write the dialogs with state 4 to mysql and those numbers seem OKish.

Any ideas?

Regards,
Andrew
