Hi All,
I have an odd issue with a client that has been occurring for a few months now. Larger updates fail to complete their download and therefore also fail signature verification. Below is a sample from the SUP's patchdownloader.log. The pattern that occurs is the same for each failure. The download begins and shows progress at 10% intervals. Exactly 5 minutes after the download begins, it acts as if the download is complete, regardless of the actual progress and attempts to verify the signature. Since the download is truly incomplete, the signature verification fails. Any patch that takes longer to download than 5 minutes sees the same behavior.
A manual download of the file in web browser is successful. While the site is somewhat bandwidth constrained, the underlying network does not have issues. No proxy server or web filtering is in place. It feels as if this is some sort of timeout within SCCM, but my research has not been able to uncover any documentation to support that theory. Thoughts?
Thanks in advance!
