Hi

Please try this:

DiamondManager webServiceManager = new DiamondManager();

webServiceManager.Timeout = 600000;

webServiceManager.Login("user", "pass");

UploadLotsParameters uploadManager = new UploadLotsParameters();

KeepAliveParameters aliveParameters = new KeepAliveParameters();

aliveParameters.KeepAliveType = KeepAliveTypes.AllMemberLots;

webServiceManager.KeepAlive(aliveParameters);
