.net - Arithmetic overflow in IIS when loading 8 gb to memory in application start -


i've got web service needs return responses real time (under 100 milliseconds end end) needs hit 200 million record listing. due this, our architect has decided load whole thing memory on application start, uses 8 gb of memory. on local machine runs no issues, when put in iis 8 on our test box run error:

[overflowexception: arithmetic operation resulted in overflow.]    ars_webservice.global_asax.application_start(object sender, eventargs e) +197

my guess iis worker process giving up, and/or doing memory clean due size used, i've set app pool not reset due memory.

edit: solved, nothing size of iis worker, entirely due system differences converting between intptrs , strings.
