If this is with a particular distribution, it would be wise to check with the
distribution support or bug entries.
It would be helpful to supply a bit more information. What processor is this
being run on? What are the events that the performance monitoring hardware
measuring? Are there any messages in /var/log/messages related to oprofile?
You might try getting the daemon to provide more information with:
opcontrol --start --verbose
Then take a look at /var/lib/oprofile/oprofile.log and see if there are any
messages showing the samples being dropped.
