SMS: Sender Does Not Respond to Schedule or Rate Limit Changes (317893)


The information in this article applies to:

  • Microsoft Systems Management Server 2.0
This article was previously published under Q317893

SYMPTOMS

You may experience a problem when the Sender component of the Systems Management Server (SMS) Executive service has begun transmission of a package to a remote SMS server site. During the current site-sending job, the Sender component may not accept changes to the Address properties.

Example

The sender has begun sending a 600 megabyte (MB) file to a remote site, and the address for that remote site has a 50 percent bandwidth-use throttle or rate limit. If the rate limit is changed to 100 percent during the sending process, the sender thread does not detect the change to the address properties. When this occurs, the sender thread continues to send at the 50 percent limit.

This limitation applies to both the rate limit and the outbox availability schedule. Because of this, if the schedule had been closed for this address after sending had begun in the earlier example, the large package file would still be sent to the remote site. The sender does not stop sending data to the destination site until it has completed the sending of any package that is currently in progress.

Even if you try to stop the SMS Executive service, in progress send requests do not stop, and the SMS Executive service does not stop until the current sending job is done.

CAUSE

The sender thread loads an address' rate limit and schedule upon creation, and it does not refresh the address information while the package and instruction file are being sent. Because of this, the sender adjusts the sending rate according to the schedule when the thread is started, but it does not adjust for any changes that occur after the thread has been created.
