Out of Memory errors in C#.net , Dotnet 2.0 pool -


one 32 bit c# application( dotnet 3.5, hosted on iis) facing out of memory errors. application hosted service , loads data(about 4 million records db) memory cache( dictionary) every night. earlier running 1.4 gb( w3wp.exe) , highly unstable , after removing db data ( 17 million 4 million), memory reduced 0.4 gb reduced out of memory errors still appearing.

ram available , believe dotnet code shows kind of error between 0.8gb 1.2 gb. so, possibly cause this?

any idea, if temporarily can done without changing code iis or memory paging etc perspective.

regards

in .net maximum object size 2gb. if reason object reading data exceeds 2gb threshold crash out of memory exception regardless of whether 32 or 64 bit or how memory have available.
