ModbusClient.Available() Has memory leak

[3D-Lasers-Lab]

Every time the Available() method is called the program uses about another 100k or RAM.

Here is the associated code for ModbusClient.Available()

Doesn't look like either implement IDisposable System.Net.NetworkInformation.Ping so doubt using(System.Net.NetworkInformation.Ping pingSender = new System.Net.NetworkInformation.Ping()) would help?
There are some cleanup Internal Dispose methods but they are not public.

Are you sure it's a memory leak and not just a delay until the Garbage Collector cleans it's up once goes out of scope?
100K does seem high, how did you check for that use?

public bool Available(int timeout)
{
// Ping's the local machine.
System.Net.NetworkInformation.Ping pingSender = new System.Net.NetworkInformation.Ping();
IPAddress address = System.Net.IPAddress.Parse(ipAddress);

        // Create a buffer of 32 bytes of data to be transmitted.
        string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
        byte[] buffer = System.Text.Encoding.ASCII.GetBytes(data);

        // Wait 10 seconds for a reply.
        System.Net.NetworkInformation.PingReply reply = pingSender.Send(address, timeout, buffer);

if (reply.Status == System.Net.NetworkInformation.IPStatus.Success) return true; else return false; }

Good morning. I never experienced this bug before, but to be completely honest timeout in Send(address, timeout, buffer); in System.Net.NetworkInformation namespace is of type TimeSpan which is a struct and not int.
Is this issue related to boxing and unboxing timeout?
