SQL 2012 Uses all RAM then crashes the Machine

I have a SQL 2012 SP1 running on win 2012 R2. I have 80 GB for the machine. No matter WHAT I set the max ram to on SQL, it fills up the entire machine and crashes. I am currently trying to run the following to prevent this from happening, yet I do not think this is really working. EXEC master.dbo.sp_executesql N'DBCC DROPCLEANBUFFERS' EXEC master.dbo.sp_executesql N'DBCC FREESESSIONCACHE' EXEC master.dbo.sp_executesql N'DBCC FREEPROCCACHE' EXEC master.dbo.sp_executesql N'DBCC FREESYSTEMCACHE ([ALL])' EXEC master.dbo.sp_executesql N'DBCC FLUSHPROCINDB( 7 )' A long time search of this has revealed that this happens and the answer is "more ram". My database is 17 Gigs. This appears to be a lot for this. The 2012 server is using a linked server to the 17 gig database. The 2012 server is being hit by Crystal reports that simply use views to the linked server and database (sql 2005 not an issue). Is there some type of formula where you can decide on ram? I have a lot of individals asking why is the database cached 4 times and still wanting more? I have optimized for adhoc queries and this has produced little results.

Up to 2 attachments (including images) can be used with a maximum of 512.0 KiB each and 1.0 MiB total.

is sql server the only thing on this machine? what is the current value of "Maximum server memory (in MB)"? The linked server jumps out - linked server memory usage is not limited by max server memory. You might try some of the virtual address space queries in this msdn blog to see if you can identify something outside of the buffer pool that is driving this memory usage - http://blogs.msdn.com/b/sqlserverfaq/archive/2010/02/16/how-to-find-who-is-using-eating-up-the-virtual-address-space-on-your-sql-server.aspx

So you have 80 GB of RAM on this server, right? Your database it only 17 GB, right? What is your 'max server memory' set to? please run this -- exec sp_configure 'max server memory (MB)' -- and post back. What does Performance Monitor show for "SQLServer:Buffer Manager\Page life expectancy" and "Memory\Available MBytes"?

Here is the memory results, as stated no matter what I put in here it does not appear to make any difference. name minimum maximum config_value run_value max server memory (MB) 128 2147483647 60144 60144

Page life expectancy Average is 161,286.205 , min = 155 and max = 167 over about 4 hours today. I can go back to previous days. No other apps no CLR. Just Crystal running views. Current Memory perfmon counter disappeared along with a few others but current memory is 42.7 GB in use 37.3 GB available 44/106 GB committed 1.6 GB cached 180 MB paged pool 186 MB non page pool. I have been running the DBCC to try and keep the thing to a minimum growth pattern.
