Backlog limit exceeded error and freeze in CentOS 6

Two solution levels:

 1) Raise auditctl buffer:

Modify "-b 320" in /etc/audit/audit.rules  and raise to 8000 or more

restart daemon :

service auditd restart

and execute command:

 auditctl -b 8000

2) Disable audit:

/etc/init.d/auditd stop
chkconfig auditd off
