Hello,

the problem occurs only on one of my servers. I tried to find the 
difference. It is the bind9 (bind-9.10.3pl3). If I stop the bind9, tcpdump 
works without problems. When I restart the bind9, the CPU load goes back 
to 100%.

Is it a problem of the kernel, tcpdump or bind9?


Thank you for your efforts
