Hello,  
I am having issue with auditbeat service running, but there is no output and some commands are not working. Found this error in syslog:

should I set rate\_limit and backpressure\_strategy ? or what are recommended values ?

thank you

I am facing this issue when I am first stopping auditd running on the server and than starting auditbeat. Looks like it helps if I before auditd stop flush audit rules with auditctl -D but I still don't understand which buffer is overloaded. Do you please know how netlink audit socket buffer works ?  
thank you
