User gets the below shown error in Presentation Services when he try  to issue any requests to OBI Server.

Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43081] Illegal operation attempted on a closed session. (HY000)

The most possible reason for this error is : 
The BI Server Administrator might have disconnected the current user's session and that user might be still sending request to the BI Server.

Solution :
When the BI Server Administrator disconnects USER from the current session, then such user can not send request to the BI Server. Because that user in no more in the session to request.

Solution : Log out from the Presentation Services (just click on the Log Out button) and again Log in and check the same request.
