The static objects of the web service are swapped out.

[cycheng]

I write a web service which holds a static hashtable
At the first method invocation, the constructor loads the hashtable
then the look-up method of the web service can run quickly by look up
the pre-loaded hashtable
My question is, if the web service has not called for a period of the time
the memory used by the hashtable seems to be swap out
Then the look-up method will take a long time
It is even longer than the time to load the whole hashtable
I want to emphasize that the web serivce does not be recycled
I have the log code to show the constructor does not called again
Anyone has the solution

What version of IIS are you running? In IIS 6, by default applications are
configured to shut down after a specified time period. If your application
is unloaded, then all of your static instances will be reloaded. Depending
on static instances in a web service is a problem in the general case - in
ideal scenarios a web service should be able to be restarted at any time.
Can you back that data up in a database?
