Query Resource Semaphore Max Memory

Hi Folks,

I'm on SQL2005 32-bit and am suffering from memory contention problem.

I do have AWE setup for 10485760 kb but it doesn't seem to suffice.

Looking at dm_exec_query_resource_semaphores I see that my queries are queue'ing up to get memory allocated.

Now, of course the correct direction here is to fix the queries that are eating all the resources but this is a very old environment with many bad queries which have just exceeded the tipping point.

What's interesting is that despite having 10GB awe, the column max_target_memory_kb indicates only 750MB.

Is there any way to grant more memory to the semaphore as a temporary solution?
