Network Hangs - Leopard/Debian
I've come here as a last resort (while I've still got some hair left) - I've been looking high and low for a solution to this problem, but there are simply too many possible sources for me to comb through - I'm just above newbie level.
What happens is that I periodically lose my connection to my debian (amd64 Etch) servers that I am using for NFS/(mac)FUSE mounts. The problem persists across both type of mounts. My setup: an OS X "head" server controlling (through 1000T ethernet) four Debian Etch sub-servers, each with their own SATA storage space.
After much testing and troubleshooting I've managed to eliminate our switches from the problem - and in doing this I found that, in fact, data transfer has nothing to do with the problem. The sub-servers will disconnect whether there is data being transferred or the server is completely idle. The disconnect (hang) can happen anytime - while logging in (connect timing out) and at varying periods (10min ~ 2hrs).
I'm not asking anyone to solve this problem for me, but could one of you be so kind as to point me in the right direction about which logs to consult to find the source of the problem, or which test commands to run?
Thank you, Best,
random network hangs (OS X)
I am facing exactly the same problems as Sefu (no hairs left on my side).
I am using a mixture of OS X clients (Tiger, Leopard, Snow Leopard) with NFS and MacFuse (SSH) over an Ubuntu 9.04 Server (Jaunty) 64bit.
As Sefu I have tried everything (as low level as checking cables/swithes/tcpdump) and came to no conclusion. I noticed that things gone worse with Snow Leopard.
In the same network I run a bunch of linux Ubuntu clients with no problems at all.
Did someone solved this?
