[SR-Users] Problem with ghost dialogs

[Joel Serrano]

Hi Cyrille,

As Alex pointed, if you could share more info it would help try to identify
the cause.

Here is one possible guess:

Are you replicating dialogs vía DMQ by any chance? I have run into ghost
dialogs in the past and they were narrowed down to being replicated via DMQ
from another node, and that was caused in the first place because of a
restart of kamailio or a sudden problem etc., no other node would own those
dialogs so the timeout timers would not apply, and the
restarted/problematic node has no way to know that he owned them in the
first place, leaving them orphaned for ever blablabla...

Joel.
