Hello !
First, sorry I don't speak English very well :p Usually speak French !
I have a problem with a FreeBSD server that is far far away, so I don't
have access to the console. As far as I know, it worked fine with
4.2-RELEASE for... hmm, 2 days, then I upgraded it to the latest STABLE
(4.3-BETA), and the server worked fine for 24 hours or so, but then, the
server locked up. It was still answering to pings, but all daemons
weren't responding anymore. I could still telnet to it, but I was just
not getting the login prompt, same thing for Apache, FTP, SSH... I can
connect, but no answers.
I asked to reboot it many time. And each time, I can telnet to it, and
get the login prompt (!), but that's strange... seems it can't fork a
shell... I don't even get the motd, just the "Last login from..." thing.
But sometime SendMail is working, and I could send mail to the account
previously created on the machine. But all the servers always die in
something like, 5 minutes.. Then it still answers to pings, but just no
answers from Telnet/Apache/FTP, etc... :(
However, the technicians there were able to do a make world in single
user mode, worked fine. But in multi user mode, the server seems to
consume all his ressources, and then processes start to crash randomly,
and there is also files corrumption, and always some kind of error
messages like "Cannot kill process", things like that, they don't know
what's causing this.
Of course, technicians there want to bill me 100$ to reinstall
4.2-RELEASE.. hehehe :p But luckily, I've backuped a 4.2-RELEASE kernel
in the root. So, now, the computer does exactly the same thing with the
4.2 kernel, exactly. But those technicians still says that the problem
came from the 4.3-BETA environnement (hmm, the "world" !), not the
kernel, nor the hardware, so they have to "repair" what I've broken ($).
:(
So, is it safe to say that the world is indenpendent of the hardware so
this problem should reproduce on all 4.3 system around the planet
(Hehehe, personnaly, it works fine on my computer ! :p), or could this
really be a bug NOT in the FreeBSD kernel that causes the machine to die
in 5 minutes or so in multi user mode (even will it is idle !) ?
Thanks ! And sorry for this long long long e-mail :p
I've attached a DMESG from 4.2-RELEASE, sorry... I don't have a more
recent one.
