Greetings,
We have had simular problems with 3c905b on a linux2.2.x box. Its a heavly
used box handling a lot of packets (IRC server + WWW server). The host
randomly locks up. If we catch it promptly (within a minute or so) we can
config down/up the interface and its fine. Otherwise it begans
I think I see a flaw with this...

Why not do an:
fd = open(file, O_RDWR);
fstat(fd, fi);
lstat(file, li);
if (fi.st_ino == li.st_ino fi.st_dev == li.st_dev S_ISREG(fi.st_mode)) {

That guarantees that the directory structure reflects your file descriptor.

I am currently researching the problem, and will post an upgrade for 1.6* within 24

The only problem I have with ifconfiging down/up is that every time I've run
my test, the machine completely locks, no keyboard, no nothing... So
ifconfig is not an option at that point. Unfortunately, when it crashes, it
crashes BIG. Also, I should have mentioned in my first mail that when using

Hi,
when you're dealing with files in /tmp that are supposed to be re-opened
(rather than opened once and then discarded) there's an established
way to do it which goes like this:
if (lstat(fname, stb1) = 0 S_ISREG(stb1.st_mode)) {
fd = open(fname, O_RDWR);
