Server crash on creating cache item

[vietphung97]

Hi,
I've just implement MVCdonutcaching for my web apps. Everytime (~20-30 times) I browse app with donutcaching enable, server was freeze for a few secs then continue to work. But when I clear all cache item then refresh the browser, it's freeze again. I used MongoDBOutputCache but it's still happens with origin MVCDonutcaching.

I have check event viewer and this's what i got from it:
"Windows successfully diagnosed a low virtual memory condition. The following programs consumed the most virtual memory: vbc.exe (3644) consumed 8264318976 bytes, mongod.exe (2948) consumed 2925314048 bytes, and devenv.exe (6016) consumed 900939776 bytes.".
My server has 8GB DDR3 with SSD, application run fluently with no delay without donutcaching.
Anyway to fix that?
Thanks.
