opensuse11.1 loses network connection

[Andrew Kaplan]

Hi there --

One of our servers had opensuse 11.1 installed as an upgrade from opensuse 10.3 on Monday of this week, and has lost its network connection twice in as many days.

The network cards on the server, of which one is currently in use and the other is up with the same ip address but not currently connected to the network, are the NetXtreme BCM5722 gigabit ethernet PCI express model. The cards are configured to run at 100Mbps Full Duplex with Autonegotiation turned off.

A check of the Online Update utility, with the filter set to Needed Patches, did not list anything at the present time.

Has anyone seen this before, and know what the cause is as well as how it can be

I'll suggest to check syslog/dmesg.

I don't think having two interfaces with the same address is a good idea, does it even work?.

Try using bonding if you need redundancy... As suggested, check the logs.

Hi there --

The issue turned out to be the antivirus software, ClamAV, scanning the /dev, /proc, and /sys directories that caused the network connection to reset.

The solution was to exclude those directories from the scan, and once that was done the problem no longer manifested itself.
