* The output of "`cpstat cpsead`" command on the Correlation Unit Server shows:

  ```
  
  [Expert@HostName:0]# cpstat cpsead
  
  Process is alive:   1
  Connected to SEM:   1
  Logs Processed:     0
  No Free Disk Space: 1
  
  Process Status:     2
  Short Description:  No free disk space
  Long Description:   There is not enough disk space available on the Correlation Unit.
  Please free disk space. The minimum disk space percent that should be free is configured in $FWDIR/conf/eventia_general_properties.C
  ```

## Cause

If the Correlation Unit has no connectivity to the SmartEvent Server, it stores the events until connection is resumed.  
To make sure that there is sufficient disk space, a check that at least 15% of the disk is free is performed.  
If the disk has less than 15% free disk space, the above message is displayed.

**Important:** The Correlation Unit will be shut down if this problem is not resolved.
