[OpenSIPS-Users] An error exists in recording the number of ongoing sessions at RTP Proxies

[microx]

Hi all,

I still have no solution to this issue. The relevant code of my script about
the statistics is attached in the previous post and list below. From the
source code of set_dlg_profile in dlg_profile.c (see the following), I doubt
the cause is profile value is not protected by a critical section. Any help
is appreciated so much.

Best regards,
Chen-Che

source code of set_dlg_profile in dlg_profile.c
/* set the value */
if (profile->has_value) {
    linker->value.s = (char*)(linker+1);
    memcpy( linker->value.s, value->s, value->len);
    linker->value.len = value->len;
}
