Re: [Samba] Streaming large videos causes server's networking to crash
Well, I figured it out. Turns out the problem was actually the Linux kernel itself. The bug report is here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/347711 Just as the comments suggested, changing to the mainline kernel has apparently solved the problem. I've been playing video for 18 hours solid now and everything is fine. Thanks for your assistance guys. -- Paul A.

[Samba] Streaming large videos causes server's networking to crash
Greetings all; I really hope someone can help me. I recently upgraded to the most recent version (from a year-old version) of Samba, on a server now running on Ubuntu Server Jaunty Jackalope x64. After upgrading, whenever I play large media files on my Vista machine streamed from the Samba server, the networking functionality on the server drops out. Sometimes it happens after playing a video for 2 minutes, sometimes it takes 2 hours. After it drops out, running /etc/init.d/networking restart on the local terminal restores networking functionality. Rebooting also has this effect. This never happened before I upgraded, so I doubt it's a hardware problem.

Which network device are you using? when it happens, do a dmesg|tail on the server. Anything interesting there? I had a similar symptoms which turned out to be caused by the Realtek device on my motherboard and the driver in my Linux distro.

Re: [Samba] Streaming large videos causes server's networking to crash
I swapped the motherboard because I had too much downtime and wanted to take it out of the equation - it turned out to be a faulty sata data cable. I used a driver downloaded from realtek.tw - this is obviously off topic here - but it's comforting to the team that this is probably not a SaMBa problem. Just search for info on driver issues with that netcard and your OS. Which driver is in use?
