Apparently I missed something somewhere...  

Errors in file /oracle/diag/rdbms/test/TEST/trace/TEST_pmon_16980.trc: ORA-56703: VKTM process died unexpectedly Mon Sep 15 22:16:47 2008
Error occured while spawning process q001; error = 56703 PMON (ospid: 16980): terminating the instance due to error 56703 Mon Sep 15 22:16:53 2008
Termination issued to instance processes. Waiting for the processes to exit
Instance termination failed to kill one or more processes Mon Sep 15 22:17:15 2008
Instance terminated by PMON, pid = 16980  

[oracle_at_srv trace]$ oerr ora 56703

56703, 00000, "VKTM process died unexpectedly"

// *Cause: An explicit kill or internal error caused the death of VKTM
//         background process.
// *Action: Restart the instance.

Apparently that this is serious enough, my instance crashed and to my surprise without something like a ORA-0600 (maybe because "it is handled..."), although I can imagine that this process, apparently with dependencies with PMON, will cause the other important backgound processes to shut down (if not already the case).  

For those who are interested this happened after trying to insert a lot off big xml files into a binary xml xmltype, table which caused a lot of ORA-04030, that caused job queue processes to die, that caused server (shared server) processes to die, that signaled pmon to terminate the instance.    

So my question...  

Does anyone know what a "VKTM" background process is...?
