Comment 9 for bug 1312362

The Samba developers are pretty adamant that this isn't a bug in any version of their software. They place the blame for this problem squarely on the shoulders of Iomega, Zyxel, and anybody else who modified their code for their NAS boxes. The problem, apparently, is that newer versions of Samba hit servers with multiple requests at the same time, and for some reason the Zyxel and Iomega boxes can't handle this. The best solution they've come up with is to modify the smb.conf file on your server to include this setting: "max mux = 1".
