wmi memory leak?

[cs]

if I repeatedly call the following method on my winxp machine (and many
others) the svchost.exe process increases its memory very very quickly, and
doesnt go back donw, I have machines that after a day have svchosts taking 1
gig of ram, thank god I have 3 more to spare!

public static void GetNetworkProperties(String NetConnectionID)

{


try

{

SelectQuery sq = new SelectQuery("select * from Win32_NetworkAdapter where
NetConnectionID=\""+NetConnectionID+"\"");

ManagementObjectSearcher mos = new ManagementObjectSearcher(sq);


foreach(ManagementObject mo in mos.Get())

{


foreach(PropertyData data in mo.Properties)

{


if(data.Name.Equals("Index"))

{

ManagementObjectSearcher query1 = new ManagementObjectSearcher("SELECT
DefaultIPGateway,IPAddress,DNSServerSearchOrder,DHCPEnabled,IPSubnet,MACAddr
ess FROM Win32_NetworkAdapterConfiguration where Index="+data.Value);

ManagementObjectCollection queryCollection = query1.Get();

String[] ips = null;

String[] dns = null;

bool dhcp = false;

String[] subnet = null;

String mac = null;

String[] gateway = null;

foreach(ManagementObject adapter in queryCollection)

{



foreach(PropertyData prop in adapter.Properties)

{


switch(prop.Name)

{

case "IPAddress":

if ( prop.Value != null)

{

ips = (String[])prop.Value;


}

break;

case "DNSServerSearchOrder":

if ( prop.Value != null)

{

dns = (String[])prop.Value;


}

break;

case "DHCPEnabled":

if ( prop.Value != null)

{

dhcp = Convert.ToBoolean(prop.Value);

}

break;

case "IPSubnet":

if ( prop.Value != null)

{

subnet = (String[])prop.Value;


}

break;

case "MACAddress":

if ( prop.Value != null)

mac = prop.Value.ToString();

break;

case "DefaultIPGateway":

if ( prop.Value != null)

{

gateway = (String[])prop.Value;


}

break;

}

}





}


}

}


}

}

catch(Exception exe)

{


}


}
