ASP.net site Hangs at App Pool Recyle with 100% CPU Usage
This is becoming a serious problem for us, the ASP.net website - w3wp.exe max at 100% when the Application Pool recycles. This does not happen every single time, it happens once a day, at random intervals. We've migrated from Memcached Server 1.0.3 to Membase 1.6.X.
Could someone point us on how to debug this issue? This is really causing us headaches in production.
We are using Membase 220.127.116.11-win64 on IIS 7, Windows 2008 Datacenter Edition, we created a memcache bucket in membase, membase is installed on one server + the same server as the web server.
We are using the latest Enyim client, following the code suggestion given in its wiki.
There are no error messages in the event logs.
Could someone please tell me where do I start the debugging from? How do I see more errors if any? There are no exceptions generated by us, and when it hits 100% cpu, the log writing stops.
