Description (partial)

Symptom:
subdb_svr crash after modifying User Profile in RADIUS

Conditions:
a.	As part of pppoe subscriber bring up, User Profile is downloaded from RADIUS after successful authentication of subscriber.

b.	User profile attributes are of 2 types.
•	Simple/single value attributes
-	Service-Type = Framed-User 
•	Multi value attributes
PQoS_5Mbps_OUT         Cleartext-Password := "cisco"
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,BROADBAND_VOZ),police(1536,transmit,drop),pri-level(1),set-cos(5))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,BROADBAND_CRITICOS),bw-rpct(50),set-cos(1))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,BROADBAND_BUSINESS),bw-rpct(35),set-cos(1))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default,class-default),bw-rpct(15),set-cos(0))",
                cisco-avpair += "ip:qos-policy-out=add-class(sub,(class-default),shape(5324))"

c.	All the downloaded attributes will be converted, encoded into sysdb format and installed in subdb_svr so that relevant config can be available for subdb clients like  qos_ma, ppp_ma, ipv4_ma etc.

d.	As part of CSCup20620, a subdb internal error case is missed (as part of implementation) while installing multivalued attribute (a.k.a. qos).

e.	As part of CSCur17509, error case mentioned in step-d is handled properly.
