ERR-1029 Unable to store session info and APEX_040100.WWV_FLOW_DATA_IDX1

user8761877Apr 18 2012 — edited Jun 29 2012

after upgraded to APEX4, we start to get "ORA-00001: unique constraint (APEX_040100.WWV_FLOW_DATA_IDX1) violated" error once for a while for an 3 years old APEX application.

After install the newest 4.1 patch, we got error message like "ERR-1029 Unable to store session info. session=1174833697260001 item=2977423879379107 ORA-00001: unique constraint (APEX_040100.WWV_FLOW_DATA_IDX1) violated".
The item is an hidden item on the page, nothing fancy at all. And the error message point to a different item at different time.

It is hard to reproduce. But users got it sometimes.

We use 11g database.

Does anyone know what is the cause? Please advice.

Thanks.
