connection leak

[feedly team]

My application is leaking connections somehow, it runs fine for days
continually doing requests but then at some point timeout connections start
to occur continuously. I am using the ThreadSafeClientConnManager to do
requests. I execute http client to do a head request and to get a response.
The code is below. Are there any problems with it? What would be the best
logging options to enable to debug leaks? Thanks.

public Map<String, String> head(String publicUrl, int timeoutMillis) throws
IOException, HttpException
{

    HttpHead method = new HttpHead(publicUrl);
    configureMethod (method, timeoutMillis);

    HttpResponse response = _httpClient.execute(method);
    try
    {
        int statusCode = response.getStatusLine().getStatusCode();

        if (statusCode != 200)
        {
           throw new HttpException(statusCode, publicUrl + " failed: " +
response.getStatusLine());
        }
        ...
    }
    finally
    {
        method.abort();
    }
}

@Override
public byte[] fetchBytes (String publicUrl, int timeoutMillis) throws
HttpException, IOException
{
    HttpGet method = new HttpGet ( publicUrl );
    configureMethod(method, timeoutMillis);

    // Execute the method.
    HttpResponse resp = _httpClient.execute(method);
    int statusCode = resp.getStatusLine().getStatusCode();

    if(statusCode != 200)
    {
        if(resp.getEntity() != null)
        {
            try
            {
                EntityUtils.consume(resp.getEntity());
            }
            catch(Exception ex) {} //dropped
       }

       throw new HttpException(statusCode, statusCode + " " + publicUrl + "
failed: " + resp.getStatusLine());
    }

    return EntityUtils.toByteArray(resp.getEntity());
}
