Symptom 1
Each time the number of persistent images has reached 200 (the default is 250), the following warning message appears on the WebUI Status page. At that time, the memory size of PageFileBytes is increased.

Source : psman5

Type : warning

Event : 4140

Description: The number of persistent images has reached 80% of the limit specified by the user. Previous persistent images will be deleted when the limit is reached.

Symptom 2
After the number of persistent images has reached the maximum (the default is 250), each time a new snap shot is created, the following warning message appears on the WebUI Status page. At that time, the memory size of PageFileBytes is increased.

Source : psman5

Type : warning

Event : 4141

Description: The maximum number of persistent images has been reached. The oldest persistent image was deleted to provide space for a new persistent image.



CAUSE
When a Persistant Storage Manager (PSM) warning event 4140 or 4141 occurs, the memory size of the PageFileBytes is increased but not released. Over a prolonged period of time, a memory leak may occur in the system paging memory pool.
