Hello,

For about a week, the CommerceManager started to behave strangely. There were huge loading times, on the "Edit product" and "Add new product". And since today, it stopped working completely throwing this error :

[OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.]
   System.IO.MemoryStream.set_Capacity(Int32 value) +56

Hello,

How much memory does your server have and how much of it is being used?  What were the figures before you noticed this issue?

Hello,

The server has 4gb of memory. Before i was forced to restarted it, sqlserver process was using 1,5gb of memory. Which seems a bit to much to me...

1.5 GB for a SQL Server is not that much, but it all depends on the settings and how many applications are using SQL Server. What was the other memory used for? You should still have 2.0 GB available. Is your .NET/IIS application limited to a space it can use?

This is only a database server, with only the ecf database. No webserver, no nothing.

I think the OutOfMemory exception occurs when i make too many attempts to edit products in CommerceManager (which i explained earlier, behaves very strange).

It seems to be related to the problem i reported here : http://www.mediachase.com/Community/forums/thread/9764.aspx

Anyway, i cand send you either access to CommerceManager of the development site, or the ECF file with the XML export.

I've sent the ECF and SQL file to support.

It seems i fixed the problem. The MetaAtribute table had alomost 3 million records with null values. So i deleted them and everything looks and works fine. However, i still got this error when i go into one of the category :

System.NullReferenceException: Object reference not set to an instance of an object. at Mediachase.MetaDataPlus.MetaObject.GetElementaryFieldValues() at Mediachase.eCF.BusFacade.Filters.Products.MetaAttributesContentFilter.GetProductMetaFields(Product product) at Mediachase.eCF.BusFacade.Filters.Products.MetaAttributesContentFilter.CreateItem(Item& item, IMetaObject metaObject, String[] responseGroup, IList`1& errorArray) at Mediachase.eCF.BusFacade.ContentFilters.PopulateProductItem(Item& productItem, Product product, String currencyCode, String[] responseGroup, IList`1& errorArray) at Mediachase.eCF.BusFacade.Filters.Products.ProductSearchContentFilter.CreateProductItemsBySearch(SiteSearchRequest request, IList`1& errorArray) at Mediachase.eCF.BusFacade.ContentFilters.PopulateProductSearchItem(SiteSearchRequest request, IList`1& errorArray) at Mediachase.eCF.BusFacade.SiteManager.SiteSearch(SiteSearch search) at Mediachase.eCF.ClientLib2.ClientCatalog.SearchProducts(String searchIndex, String keywords, String[] searchFields, KeyValueAttribute[] filter, Int32 categoryid, Boolean incSubCategoryNodes, Decimal minprice, Decimal maxprice, String sort, Boolean sortOrder, String wherest, Int32 itemsPerPage, Int32 currentPage, String[] responseGroup, Int32& totalRecords, ErrorsError[]& errors)

Hi Victor,

Sorry for responding so late, but are you still experiencing the latest problem?

Thank you,

Yes, i do. However, not every product category behaves this way. Some of them are working just fine.

I read somewhere on your forum about serializing product meta-data by re-saving them.
Could this be the problem ?

Anyone ?

That shouldn't be a problem. You said SQL Server is a separate machine. If so, then what is the memory limit set for IIS application if any? And what is the amount of available memory on the web server?

The server has 2gb of memory. And the application runs in it's own Application Pool. I don't think there are any memory limits to it. Is there a way i can find this ?

In IIS 6/7 right click on your application pool, choose "Properties" and tab "Recycling". At the bottom of the opened tab there will be block "Memory recycling".

The only checked option is "Recycle worker process at the following time : 05:00"
