Infinite loop in jbuf causing deadlock

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

Looks like our new sip provider may have uncovered another issue. Using 
our other sip provider does not seem to cause the same issues, even with 
much higher calling volume. I am running the latest version of pjsip.

The problem is in pjmedia_jbuf_put_frame2. It is getting stuck in the 
while loop. I'm not sure how useful this will be but I am going to 
attach a few of the details from gdb.

I can see why it is looping, but it is not clear to me how it got into 
this state. The one thing that jumps out at me is the jb_frame_ptime = 
10. I am using a ptime of 20, and the new sip provider does as well. Is 
this unusual?

Any insight into this issue would be greatly appreciated.
