I already did it, I deleted the file /usr/local/sbin/openser and all modules in: /usr/local/lib/openser/modules/

I installed again openser 1.0.1-tls and the problem persists.

The core file has 34 Mb, so I putted it in: sip.startel.pt/core/

Thanks for the help. Joao Pereira

just to exclude the possibility of mixing between the version, please remove all openser installed binaries (modules and executable) and do a new install to get a clean installation. Also check by 'ls' for the date of the binaries to be the same.....

if still crashing, get the core backtrace.

Hello I compiled openser myself. Now I tried openser with a simpler configuration and it worked...

I had an openser.cfg that uses RTPproxy and TLS.... and the seg fault happened when I used that file. Now with a simpler openser.cfg (like the sample) just with TLS, openser started :)

I will try to find the problem in the openser_rtpproxy_tls configuration file... both files are in attachment Thank you very much for the help Joao

Bogdan-Andrei Iancu wrote:

Hi Joao,

do you compiled openser by yourself or you installed the binaries? to be able to get info from core is essential to have the correct binary.

so, to simplify the thinks, please extract the backtrace from the core by yourself:

1. enter gdb: gdb openser_binar_file core_file
2. get backtrace : bt

send me all the output of gdb from the beginning.

thanks, bogdan
