APEX_040100.WWV_FLOW_API Error while creating a Interactive Report Region

Question

I am getting the following error while creating an Interactive report region on a page. (version - 4.1.0.00.32)
Error Unable to create Dynamic Query page.
ORA-04065: not executed, altered or dropped ORA-04065: not executed, altered or dropped stored procedure "APEX_040100.WWV_FLOW_API" ORA-06508: PL/SQL: could not find program unit being called: "APEX_040100.WWV_FLOW_API"
DBA complied package but the error persists.
Does anyone know how to debug this
Thanks,

Hello ???,
We are experiencing this too at login in an application. The error is caused by violating the constraint WWV_FLOW_DATA_IDX1 on columns FLOW_INSTANCE, ITEM_ID in table WWV_FLOW_DATA. So for some reason the value of an item in session state is set multiple times.
When looking at the Access view (statement below) I see that there are multiple logins per second for a user (I have seen 12 times as maximum).
select login_name, application, access_date, count(*)
from WWV_FLOW_USER_ACCESS_LOG_V
group by login_name, application, access_date
having count(*) > 1
order by access_date descSince this count of logins varies from 1 to 12, it looks like it is not caused by the application itself, but I also don't have a clue what the root cause is.
Is there anyone else with more information on this issue?
We are on APEX 4.0 and Oracle 11g and the applications have all been built in this environment, so no upgrades have been performed.
Regards, Wouter
