c# - stackoverflow exception on System.Data.Linq.dll -

i'm working on asp.net web application. use linq sql orm data access layer (dal). in specific case of queries faces stackoverflow exception on clr level.

i use filter expression generator specific data (such load specific constrient) send more 1500 parameters store procedure.

note: consider rpc (remote procedure calling) limitation that's 2100 parameters in sql server default setting.

but don't know why face stackoverflow exception? it's interesting know problem occur on iis , no problem in asp.net web development server.

and i'm find out problem caused large number of parameters.

i grateful me?

the problem might lie in predicate you're building. when enumerate expression (which you're doing in call count()), linq sql walk down expression tree determine you're trying query. possible somewhere you're creating cyclic reference?
