You might take a look at bug 5490054 on Metalink to see if it
applies. The bug is related to Resource Manager and the SWITCH_TIME
"...But when connecting by MTS, resource manager tries to stop the session by killing shared serever process. So shared server dies and ORA-3113 is returned to terminal. Because of dying of shared server process, PMON tries to re-start shared server process, and next messages are appeared in alert.log at that timing. . found dead shared server 'S000', pid = (XX, X)"
There are a lot of bug hits on Metalink for core dump ACCESS_VIOLATION unable_to_trans_pc UNABLE_TO_WRITE - you may be able to find a possible fix, but some of those bug reports have been open for 1.5 years. What is the value of CURSOR_SHARING on the server?
