Symptoms

Tasks "Report raw traffic usage by dedicated VPSs" are always failing with /CORBA/TIMEOUT exception for Parallels Virtuozzo Containers for Windows servers.

For example:

Cause

The reason of problem is that too low memory limit is set up for MSSQL server working in Service VPS on Virtuozzo server and as a result it can not process queries from VZAgent properly.

Resolution

To solve this problem you should go to the Virtuozzo server reported in task properties (VZserver1 in this case) and proceed the following steps:

1. Open command line tool: Start > Run > cmd

2. Enter the Service VPS: vzctl enter 1

3. Launch osql.exe tool:
"%ProgramFiles%\Microsoft SQL Server\80\Tools\Binn\osql.exe" -E

4. Change MSDE memory limit as follows:
sp_configure 'max server memory (MB)',512
go
reconfigure
go

This action will increase the memory limit for MSSQL server and it will allow MSSQL server to fetch traffic statistics from database.

You may also install MSSQL Management Studio into the Service VPS (it also requires MSXML and .NET), log into it by RDP and increase memory limit using GUI:

- run MSSQL Management Studio
- right-click on MSSQL server on the very top of left pane
- choose 'Properties'
- click on section 'Memory' in left pane of the opened window
- increase the parameter 'Maximum server memory (in MB)' to 512
- click 'OK'
