Errors in the OLE DB provider.  An error occurred while loading the connection dialog box components for prompting. The following blog posts helped us identify and kill the MDX query and the user was executed: Finding and killing SSAS Sessions Kill a Session, SPID or Connection to Analysis Service Cube The problem seemed to be caused by poorly constructed Excel pivot tables.  Users can do some strange things.  Things like dragging product numbers to the columns and product descriptions to the rows.  Regardless, a single user shouldn't be able to bring down an entire server making it useless to anyone else in the company, right? For the short term we had to find a way to automatically kill queries like these automatically.  Otherwise, our team could never go to lunch together.  Someone would always have to stay behind to log the locked query and restart the SSAS service if the server spun out of control. Luckily, we were able to reproduce the conditi

All of the settings for memory are left to their defaults. http://serverfault.com/questions/116321/severe-memory-pressure-on-ssas-2008-on-windows-server-2008 When the SSAS service starts, it behaves normally. However, whenever a query is run against the instance, the SSAS service continually will consume all of the memory on the server, to the point that the server needs to be rebooted. At present, the TotalMemoryLimit and LowMemoryLimit settings are set to 80% and 75% respectively. The HardMemoryLimit is set to 0 by default. Why is SSAS using all of the memory on the server, despite the limit settings? Does HardMemoryLimit need to be set? windows-server-2008 sql-server-2008 sql sql-server share|improve this question asked Feb 24 '10 at 17:12 Brian Knight 1,042817 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted I would check the perfmon counters to confirm what is exactly using the memory - It is not clear if you are using task manager to identify the use. Analysis Service should peak out its memory at the total memory limit. Do the queries continue to run? - why do you have to reboot? is it to kill the ongoing queries? I would check the cleaner counters to see if the issue is there - ultimatel

I’ll list some potential fixes here: Close some other programs. Anything you can close down on your computer to free up memory, do it, then retry the operation that failed. Use Windows Task Manager, look analysis services at the Processes tab, and sort by the Memory column to find the biggest memory chewers. Save the file, close Excel down completely, re-open the file. Then try again. Sometimes the addin holds onto more memory than it needs to, and closing Excel down completely is a good way to “flush’ all of that wasted memory and free it back up. Switch to 64-bit Excel and PowerPivot. I highly recommend this anyway for anyone who is going to be using analysis services memory PowerPivot a lot. You’ll see the error above a LOT less, and it will greatly reduce the rate at which you see other errors too. Switch to PowerPivot V2. I don’t have a lot of hard-core production experience with V2 yet but I understand that V2 is “friendlier” when it comes to RAM usage. (Technical detail: V1 basically refuses to “page out’ to disk, and relies 100% on your physical RAM. V2 allows for some paging, but I don’t know how much impact that will have for you. I suspect that 32-bit –> 64-bit is more impactful than V1 –> V2 but can’t be sure.) ***EDIT: PowerPivot V2 does NOT use paging, only tabular BISM servers do, so upgrading to V2 will NOT improve RAM consumption. In fact in one comment below, it was reported that V2 requires even MORE RAM than V1. If it’s happening during data import or refresh… If you are importing a large table for the first time, consider importing fewer columns if that is an option – a topic that has been covered extensively. (Fewer rows are also helpful of course). If you are refreshing a large table that has calc columns in it, those calc columns are re-evaluated during refresh. And sometimes those calc columns themselves are the reason why you run out of RAM during the import. The first thing to consider, then, is whether you can calculate those columns outside of Pow
