In alert.log file I get next message
Errors in file /home/oracle/admin/tgm/udump/tgm_ora_999.trc:
ORA-07445: exception encountered: core dump [qmcInitUgaProps()+122] [SIGSEGV] [Address not mapped to object] [0x0] [] []

and the error in .trc is in relation to full database export with system user. Part of .trc file is

ksedmp: internal or fatal error
ORA-07445: exception encountered: core dump [qmcInitUgaProps()+122] [SIGSEGV] [Address not mapped to object] [0x0] [] []
Current SQL statement for this session:
SELECT /*+rule*/ SYS_XMLGEN(VALUE(KU$), XMLFORMAT.createFormat2('XMLSCHEMA_T', '7')), 0 FROM SYS.KU$_XMLSCHEMA_VIEW KU$ WHERE KU$.OWNER_NAME=:SCHEMA1

After this error I can't connect to database but db processes are still up (I can see them with ps -ef|grep ora) and I have to restart database or sometimes and server too.

From time to time I get next error in alert. log file
*** 2005-04-08 08:41:40.454
*** SERVICE NAME:(SYS$USERS) 2005-04-08 08:41:40.454

XML DB HTTP Server: Sending error response(HTTP error code = 401)
Error stack is:
ORA-00942: table or view does not exist

Can anybody help?
