I am not seeing any SQL errors about paging, I am seeing out of memory errors from SQL and other windows components about being out of memory, which I assume...

I agree something is wrong, but it is SQL that is paging out, I start the SQL Server service and the page file grows exponentially and essentially crashes the OS,...

I have 70GB of physical memory in the machine, which is not being used much. However it is filling up the page file on the physical disk.
