Hello, CPU consumption of samba rises to 100% I am doing Achilles tests on a Linux-based server. I have noticed that during certain tests (and UDP port discovery), the temperature of the CPU cores surges to around 80-90 °C which causes the CPU clock to throttle and renders the server practically unresponsive. Following closer investigations, we found out that there is a direct link between the rise of CPU consumption by a certain process and the CPU temperature. In our case, the concerned process is Samba We are using samba4 in the full active directory mode. Environment details: OS: Ubuntu 14.04 LTS Samba version: 4.3.11 In our environment, there is a direct connection between the server running Samba and the test PC; no other element in the network. As far as we understand, this looks like a DoS attack. Certain tests render the server completely unresponsive. Is this a known issue? If yes, is there a fix for it?
