I've run into some networking issues with the 2.2.17 kernels in the SPARC
tree right now. Apparently when you do high-traffic tasks, it kills all
other things on your LAN. Other hosts become totally unresponsive and
connections to other machines from those hosts sometimes drop. Today was
spent ripping CAT 5 out, making new cables, swapping hubs, and trying new
kernels to isolate the problem.
Logan (PowerPC Slackware guy) and I discovered that all of my traffic was
bouncing through our router, even though each of us has our own segment on
the main LAN. When I would go between two machines on my segment, the
connection would bounce off our router, back, and totally congest the
other segments (collision lights on all the hubs). Needless to say, it
was quite annoying.
The problem seems to have disappeared by upgrading to kernel 2.2.18 on my
SPARC systems and disabling ethernet bridge support and 802.2 LLC support
in the kernel. Both of those options are marked as experimental and I
honestly don't know if they had anything to do with the problem or not,
but it seems to have gone away now.
My next set of upgrades will be new kernels and module sets.
Anyone else have problems like this before?
