[OpenSIPS-Users] opensips 1.6.4-2 and dlg_end_dlg

[dpa]

Hello

 

Yes the problem was there. In local route I had exec function to do
dlg_end_dlg. Thank you very much.

yes, it is, as when you do dlg_end_dlg, opensips will generate and send 2
BYEs (one to caller, one to callee); and each time opensips sends a locally
generated request, local route is triggered.

Bogdan, as I understand when I am doing fifo dlg_end_dlg through FIFO
command from console the config of  local route is activated?

Hi,

You are doing something wrong there - based on the script, it seems you do
"dlg_end_dlg", which triggers sending BYE -> local route -> you do an exec
there to do again dlg_end_dlg. So you try to do nested FIFO commands which
does not work - FIFO engine will not read a new command until the current is
not finished.

Hello Bogdan

 

The gdb  information in attachment.

Unfortunately for some unknown reason I cannot see logs. I will check the
problem and write later.

Try to set debug=4 and see the logs from the MI fifo process when running
the dlg_end_dlg command.

Also, try the get a backtrace from the MO FIFO proc after blocking. For
that, before the dlg command, do "opensipsctl fifo ps" to find out the PID
of the FIFO process.
After running the dlg command and blocking, use "gdb /path/to/opensips
FIFO_PID" and run "bt" inside - these will give some ideas on where the
process blocked.

As I understand, yes.

 

"do you see any errors in the logs?"

 

I see only "INFO:core:buf_init: initializing..." in log file

 

"also, does it recover after some time (like minutes) ?"

To speak the truth I didn`t wait recovering. I used Ctrl+Z to stop process
of dlg_end_dlg and tried another fifo command. ps -A show me that
opensipsctl process appears.

So only the MI fifo part blocks ? do you see any errors in the logs? also,
does it recover after some time (like minutes) ?

"it simply blocks and does not answer"

I can make calls. But no fifo command available.

Hi,

Does your opensips actually crashes when you run the dlg_end_dlg command ?
or it simply blocks and does not answer ?

Hello!

 

I discovered a problem with using dlg_end_dlg fifo command.

When I try to make it, dialog hasn't been ended and I cannot see in console
that command has been finished success. In /tmp directory (where
opensips_fifo is located) I found some new files "opensips_receiver_xxxxx",
where xxxxx - some numbers. Ls -la shows that files were generated when I
make dlg_end_dlg command.

Moreover after this I cannot make any fifo command. 

After opensips restart I can make any fifo command but until dlg_end_dlg.

 

There were no problems with it but recently I decided to make opensips
generates core file if it crashes.

I use this documentation http://www.opensips.org/Resources/DocsTsCrash. 

I used  "-w" option and make changes in "/proc/sys/kernel/core_pattern". May
be some problems with it?

 

Thank you for any help!
