What does this error mean?
This error means that an I/O exception occurred during a JMX call to forceUserDefinedCleanup.
Why does this error occur?
This error occurs due to a full disk preventing the cleanup from being able to run correctly and throwing the I/O exception.
How do you fix this error?
Check your disk volumes for total usage. Look for snapshots, backups, etc. that are no longer needed and remove them to free up space before attempting to use JMX to call forceUserDefinedCleanup again.
