Known Affected Releases

21.19.n4

Description (partial)

Symptom:
CP is not displaying all the chunks allocated to the UPs. New calls are failing

Conditions:
Actions done before meeting this issue (not sure the issue is lonked to those actions though):
- 2 ICSR CP switchovers done during the day
- create a new UP group
- add UPF4 to that new UP group (with removing UPF4 from its previous up-group)
- remove UPF4 from new up group
- delete the new up group
- the next day, we observed this issue with IP chunks and realized UPF4 was in "default" up group
- remove up4 from upgroup-data and add it again. up4 was then in its correct group (upgroup-data) but the issue was still there.
- "update ip-pool apn all" did not help to solve the issue
