E******* RNC high PS drop rate (35-40%!!!)

[havoc]

Hi guys,

After migrating to a new sgsn for our 2 RNC (3810), one of them is showing an extremely high PS and HS drop rate of 35-40%.

We suspect this to be false as all drive test are good, and there are no customer complaints. Initially after migration stats were good but tanked after 36 hours.

RNC has been restarted, all parameters checked and compared but still no solution. All other KPI are OK. Any one seen this or have any ideas?

Many thanks...
