It looks like there are multiple P-CSCF with same Host IP, Origin Realm + Host trying to attempt to connect to PCRF

After which PCRF blocks connection attempts from P-CSCF

btw, if you not using docker_open5gs, i would suggest to open the issue in open5gs repo

Thanks. When the error occurred, i saw there was only one pcscf. I will paste it in open5gs repo later.

Another question, i found several core dumps of PCSCF and could find the error code line with gdb bt, but not capturing the corresponding pcscf debug logs . Should I paste them here , or to the kamailio repo ?

I would suggest to paste here and also in kamailio repo. If you paste them here I can check whether I can fix it or not and push the fix upstream

For the last one, NULL pointer, some codes calling AAACreateAVP() are lack of protection. But i have no idea about how null pointer is formed.

Thanks.
