Hi, We are observing some inconsistent behaviour in one of our application (Solaris 2.6, Oracle 8.1.7). The frontend is in VC++, and when we run a query through our application GUI, the first few time it works and then (mostly after the first time) , the process core dumps with the following in the alert.log : Errors in file /oracle/admin/SMS44YA/udump/sms44ya_ora_29713.trc: ORA-07445: exception encountered: core dump [opipls()+10440] [SIGSEGV] [Address not mapped to object] [132] [] [] ORA-00600: internal error code, arguments: [12261], [], [], [], [], [], [], [] ~ The corresponding trace file has the following (warning / error ?) messages in the cursor details area: No Bind buffers allocated. This is there for all the (20) cursors. Is this the cause of the problem ? However, after I flush the shared pool, it works again. Please suggest what should I look for ?
