HTTP_RESP_STATUS_CODE_NOT_OK

Question

Hi All,
When I place any source file for processing, the message ends with the below error in MONI.
<SAP:Code area="INTERNAL">HTTP_RESP_STATUS_CODE_NOT_OK</SAP:Code>
  <SAP:P1>401</SAP:P1>
  <SAP:P2>Unauthorized</SAP:P2>
<SAP:Stack>HTTP response contains status code 401 with the description Unauthorized Authorization error while sending by HTTP (error code: 401, error text: Unauthorized)</SAP:Stack>
Earlier all went fine, but recently the server was down for sometime and then restarted all services. Since then this problem is occurring.
I have gone through similar kind of threads and as per the suggestion from those threads, have gone throughrestarting the J2EE server. But still have the same problem. Please anybody help me to resolve this issue.
Thank you

Hi Bhanu ,
SAP J2EE Engine returns HTTP response with status code 500 when many parallel users are trying to login to one application. One or several
requests may fail with HTTP response code 500 during the load scenario. In such cases, when the error happens, the following
exception must be present in the default trace of the j2ee engine .
java.lang.NullPointerException

com.sap.engine.services.security.login.LoginContextFactory.initializeLog

If this error happens in XI load scenarios, this trace is visible in the
additional information of the failed message.
Reason and Prerequisites
Reason: The authentication stack for the corresponding application is
not initialized properly.
check SAP Note - 822211 .
there is no harm in refreshing the cache also .
