My bdump trace folder grew up to 34GB in a couple of days. I've pasted a fragment of the recurring error from the trace file below. I hope somebody can diagnose this because I am not that good at low-level Oracle.

*** SERVICE NAME:(SYS$BACKGROUND) 2006-05-08 15:07:29.000

And at the end:

Google said: Your search - dbms_ha_alerts_prvt.check_ha_resources - did not match any documents. I am using ODBC Heterogeneous Services, Oracle XE Universal and Windows XP.
