Recursive CPU larger than total CPU used by the database

I have a single instance database running in HP-UX.

I have noticed that everyday at same time, between 22:00 and 22:30 the
recursive cpu shown in v$sysstat is larger than DB CPU from Time Model or
CPU used by this session from v$sysstat.

The database claims it consumed 886 second CPU but recursive cpu usage
shows 196759 centiseconds (1967 seconds).

This happens consistently everyday at the same time.

Anyone observed this behaviour before?
