Linq to SQL generates StackOverflowException in tight Insert loop
- by ChrisW
I'm parsing an XML file and inserting the rows into a table (and related tables) using LinqToSQL.
I parse the XML file using LinqToXml into IEnumerable. Then, I create a foreach loop, where I build my LinqToSQL objects and call InsertOnSubmit and SubmitChanges at the end of each loop. Nothing special here.
Usually, I make it through around 4,100 records before receiving a StackOverflowException from LinqToSql, right as I call SubmitChanges. It's not always on 4,100... sometimes it's 4102, sometimes, less, etc. I've tried inserting the records that generate the failure individually, but putting them in their own Xml file, but that inserts fine... so it's not the data.
I'm running the whole process from an MVC2 app that is uploading the Xml file to the server. I've adjusted my WebRequest timeouts to appropriate values, and again, I'm not getting timeout errors, just StackOverflowExceptions.
So is there some pattern that I should follow for times when I have to do many insertions into the database? I never encounter this exception on smaller Xml files, just larger ones.
