i had installed IIS 7.5 & SQL Server 2008 Std on Windows server 2008 R2 Std. over IBM Quad Core server with 12 GB RAM
the application is accessed from 18 locations over intranet wan and over 100 simultaneous connections are there.
the application runs smoothly and is very fast responding initially. but over time, the memory used by the server increases and ultimately IIS hangs
while checking the perfmon, the memory used by IIS and SQL shows only around 300 - 900 MB.
At first we restart the server, but now after restarting the SQL Server releases the memory from 11.8 GB to 5 GB.
I had checked several forums of both IIS and SQL Server and did all the suggestions in IIS and SQL server. but the problem persists
The server hangs once per day. after releasing the memory, the server works very well.
