Memory - Physical Memory Available Alarm
The Memory - Physical Memory Available alarm is activated when the available memory
drops below a threshold. This can result in:
- Applications
being unable to secure additional memory.
- New programs being
unable to open successfully.
- General performance
degradation due to excessive paging.
When this alarm is current you should:
- Look at the Processes page in the Processes drilldown. Check the Phys
MB column for processes using excessive amounts of memory. You
can:
- Close those applications
using excessive memory.
- Change the maximum
memory usage setting for those applications using excessive memory. Refer
to the relevant documentation to find out if this setting is supported
by the application.
- Purchase more physical
memory for your system.
- Determine if any
programs have a memory leak. To do this:
- Restart your
machine to ensure fresh memory usage by all applications.
- Use the Microsoft Performance Monitor tool and
set the update interval to 10 minutes.
- Add the Working Set Peak counter for all applications
from the Process object.
- Leave the
application running on the system overnight.
- If there
is a memory leak that can be viewed in a day, it will show up with the
Working Set Peak graph for one
of the applications rising smoothly. If the results are inconclusive after
a day, some system applications that have a memory leak may exhibit the
behavior over a week or more. Adjust the update interval to accommodate
the extended period (update once per hour or more).
