[OpenSIPS-Users] tight matching failed for BYE

[Bogdan-Andrei Iancu]

Hi,

The "tight matching" warning is because OpenSIPS gets a BYE that matches 
the dialog (based on the dialog ID), but the callee tag is bogus (see 
the logs - in the BYE request you have "15587", while in the dialog you 
have "46079"  - check the first 2 log lines, first has info from BYE, 
second from dialog).

About the crash, try to get a backtrace out of it :
