ManagementException Quota violation, Call cancelled, Provider load failure

Question

During past half of the year three users had problem which you can see below.

(Error, 27.11.2014 15:47:53+01:00) The request for Windows processes was terminated by an error.

The Provider load failure exception persists until shutdown of the application or until CTD due to memory leak (which is caused by this problem). Also I am not able to reproduce this problem, I tried call this method from test application +/- 1,5M times, but it was without problem.

Method should be OK, but you can see it below:

public static IEnumerable<Process> GetProcessesFromDirectory(string directory)
{
    if (directory.Last() != Path.DirectorySeparatorChar)
    {
        directory += Path.DirectorySeparatorChar;
    }

    var wmiQueryString = "SELECT ProcessId, ExecutablePath FROM Win32_Process";

    try
    {
        using (var searcher = new ManagementObjectSearcher(wmiQueryString))
        {
            return
                from process in Process.GetProcesses()
                join managementObject in searcher.Get().Cast<ManagementObject>()
                    on process.Id equals (int)(uint)managementObject["ProcessId"]
                let processExecutable = (string)managementObject["ExecutablePath"]
                where processExecutable != null && processExecutable.StartsWith(directory, StringComparison.OrdinalIgnoreCase)
                select process;
        }
    }
    catch (ManagementException ex)
    {
        return Enumerable.Empty<Process>();
    }
}

public bool IsProcessFromDirectoryRunning(string directory)
{
    try
    {
        return this.GetProcessesFromDirectory(directory).Any();
    }
    catch (ManagementException ex)
    {
        this.logger.Log(ex, Strings.ProcessSearchError);
        return false;
    }
}

Question is if I am getting Provider load failure can I somehow restart it? I tried to find answer on google, but I didn't find anything useful. I will be very grateful for any help.

Answer 1

Well I found that use Process.GetProcesses() and there use MainModule.FilePath is much more faster then check processes through WMI, so problems with WMI will be gone.

return Process.GetProcesses().Where(p => p.Id > 4 && !p.HasExited && p.MainModule.FileName.StartsWith(directory));
