Explanation:  There might be a disk problem or a volume containing a swap file might have been dismounted when there was no other swap file to hold the data. Applications that use virtual memory, such as Java applications, might start to fail; if so they will be unloaded.

Action:  Reload any virtual-memory applications that have been unloaded. To prevent the problem from happening again, do not dismount a volume containing a swap file unless there is a swap file on another volume to store the data.
