[OpenSIPS-Users] tight matching failed for BYE

[jing]

hi,Bogdan!
  Very thanks for your reply. It's helpful. I found that sipp sent a wrong tag in dialog when the number of calls increase.
 For the other question, I will see the document you sent to me .
 Thank you .
 Kind regards,
 Jing

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 :

  hi,all
 I used sipp as UAC to test 500 current calls on opensips, when the Total-calls reach to about 30000, opensips crashed. And the log shows as below:

 I can't understand the log. What caused the error?
