Consider the following scenario. You create a linked server in Microsoft SQL Server 2005. Then, you use Unisys OLE DB Data Provider for ClearPath MCP as an index provider to access data from a Unisys Enterprise Database Server (DMSII) database. You run several linked server queries successfully. In this scenario, you may receive the following error message when you run a linked server query against the provider:
The oledbprovider unisys.dmsII.1 for linkserver "<ServerName>" reported an error. the provider ran out of memory
Additionally, error messages that resemble the following are logged in the SQL Server 2005 error log file:
2007-04-05 13:14:27.410 spid59 Failed Virtual Allocate Bytes: FAIL_VIRTUAL_RESERVE 589824
2007-04-05 13:14:27.440 spid59 Error: 701, Severity: 17, State: 123.
2007-04-05 13:14:27.440 spid59 There is insufficient system memory to run this query.
Note This problem also occurs when you use other index providers as the linked server.


This problem occurs because a memory leak occurs in SQL Server 2005. The memory leak occurs because the memory that is allocated when SQL Server 2005 calls the IRowsetIndex::GetIndexInfo function is not freed.
