Hi! Our web server just went offline after the following kernel warnings: > Feb 21 11:02:59 c0w /kernel: vr0: no memory for tx list > Feb 21 11:03:30 c0w last message repeated 11 times Is this the result of a new kind of DoS attack? The server has 1 GB RAM and runs 4.1.1-STABLE, the kernel parameters are supposedly set up to handle the traffic of a busy web server. Any hints? netstat -m shows that the peak number of mbuf clusters was the max (4608), so that was the problem. What would be a safe high value for NMBCLUSTERS? Thanks, Marinos -- ***==> Marinos J.
