There was a rather large upload today. Perhaps you were syncing while the upload was happening?
Neal, I sync my repository 3 times a day, at 6am, 2pm and 10pm. This has been happening for the past couple of days.
This is what was in the email from my 2pm rsync session
rsync: failed to connect to distro.ibiblio.org: Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(122) [receiver=3.0.4]
This problem is not being cause because I have been trying to rsync during an upload. I could understand 1 or 2 perhaps even 3 times. but this has now happened over 12 times in a row each time being separated by a 8 hour time span.
