I found the problem back at the end of October and narrowed it down as much as I could but didn't know where to report it until now. For complete details please see the rsync mailing list archive at http://lists.samba.org/pipermail/rsync/2000-October/003004.html and some of the preceding and following messages. In particular, the next message http://lists.samba.org/pipermail/rsync/2000-October/003005.html is an interpretation of the TCP dump by my co-worker which implicates the Linux side. Also, in http://lists.samba.org/pipermail/rsync/2000-October/002985.html Andrew Tridgell refers to a TCP patch that went into Linux kernel 2.2.17 and that "Stephen" told him about it but I don't know what Stephen he was referring to; that fix didn't help anyway. The first message above refers to a set of data that could possibly be used to reproduce the problem, but unfortunately nobody else has reported to me that they have successfully reproduced it. I only saw the failures when using rsync to pull to a particular Solaris 7 workstation, but it happened when pulling from two different Linux machines and three different kernels but no other type of machine. Another message http://lists.samba.org/pipermail/rsync/2000-October/002981.html gives a more complete rsync command for reproducing the problem. The original report at http://lists.samba.org/pipermail/rsync/2000-October/002964.html says that I first noticed the problem on Linux kernel 2.2.16-3smp. - Dave Dykstra - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
