Objet : [Nut-upsuser] stopping ups services resets my network

Hello,


I have this issue: ups is working fine for a time but when I stop the
services or if I unplug the ups device (over usb) I get the following in
/var/log/messages

I am running nut-2.4.1 on RHEL4.

duplex.
Sep 28 15:04:38 mabolas kernel: tg3: eth0: Flow control is off for TX and
off for RX. 

As soon I kill usbhid-ups, I lost my ssh connexion. Logs say ssh is lost
after 15m but in fact I couldn't type anything just after the ups stop. The
network is resetted 15 minutes later. 

It appears this error occures only when nut has run for some days (4 days in
this case). When stopping ups after few hours, nothing happens.

I also have noticed some wierd behaviours on other applications that might
be related. I'm not so sure it is the same so I will make a seperate thread
when I have more debug info on that.

Can you help me fix this?

Regards,
Antoine
