Custom counters file view is out of memory

Hi,

For some reason this exception is thrown by our application, when attempting
to retrieve a performance counter:

ExceptionName: System.InvalidOperationException
exceptionMessage: Custom counters file view is out of memory.

Searching for a solution revealed that others have seen this error but
nobody knows whats happening. A fix has been offered:

"I did a brief investigation I am wondering if you are using lots of
performance counters.
I found that there is a .config setting that controls the max fileView
memory size. It is

<configuration>
<system.diagnostics>
<performanceCounters filemappingsize="524288" />
</system.diagnostics>
</configuration>

(see the filemappingsize attribute in the performanceCounters element)"

But id much rather fix the problem instead of doing the above in a live
environment hoping for the best.

In hopes of an answer...
