We keep having a nagging problem with our SQL Server. I don't know what changed, but we started having out of memory errors every 3 weeks or so.

I thought I could locate something strange with DBCC MEMORYSTATUS, but I have to admit, I'm not very good at understanding the output (and we don't have a DBA on staff).

Could someone take a look at the output and tell me if there is anything odd? Are there any other things I need to look at? Thanks.

EDIT: Full output is here: DBCC MemoryStatus

do you have one instance of sql server, or do you have multiple instances on one box? – JonH Oct 3 '12 at 15:43
One instance as far as I know – Dan Oct 3 '12 at 15:44
I was going to say I we had similiar issues but we found our issue due to multiple instances on one server. Memory was not allocated properly to each instance. But yours might be a different issue. – JonH Oct 3 '12 at 17:05
I found something about .NET applications that use a connection string with the default packet size of 8KB causing problems with the virtual address space. Our website was using the default. I've changed it, but I guess the only way I'd know if that's the problem is wait and see. – Dan Oct 3 '12 at 17:32
What were the specific errors? – Thomas Stringer Oct 4 '12 at 13:49
