Hi there. Out of curiosity, what kernel/distribution are you running, or is this a custom kernel compile? Can you also share the output of 'auditctl -l' from your system? The general approach taken by everyone to turn-off the per-syscall audit overhead is to add the "-a never,task" rule to their audit configuration: # auditctl -a never,task If you are using Fedora/CentOS/RHEL, or a similarly configured system, you can find this configuration in the /etc/audit/audit.rules file (be warned, that file is automatically generated based on /etc/audit/rules.d). -- paul moore www.paul-moore.com
