I think it's the same problem I had and it's not the network problem. It's about a problem with system on IDE drives. After I switched to a SCSI disk for boot, swap and root the problem disappeared completely. The fact that the problem doesn't occur with 10 Mbps connections only shows that slow ether cannot create enough stress for the problem to manifest itself. It's some racing condition in UDMA driver. If you disable DMA on your system IDE drive you won't have the problem but the performance really sucks. _____________________________________________________________ Get 25MB, POP3, Spam Filtering with LYCOS MAIL PLUS for $19.95/year. http://login.mail.lycos.com/brandPage.shtml?pageId=plus&ref=lmtplus -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
