Server is shutting down

Hi,

I'm working with OAS 9.0.4 on AIX 5.2. I'm trying to run reports but I get the following error message:

REP-500002: Server is shutting down.

And sometimes the following error message:

REP-52266: The in-process Reports Server rep_test failed to start.exception oracle.reports.RWException {
oracle.reports.RWError[] errorChain={struct oracle.reports.RWError {
int errorCode=52266,
java.lang.String errorString="The in-process Reports Server rep_test failed to start.",
java.lang.String moduleName="REP"
}}
}

I made a trace of the report server and collect the following data:

[2006/1/21 4:15:33:415] Exception 50001 (): Server is initializing
exception oracle.reports.RWException {
