ENRICHED log_format not encoding all parameters

Hello together, I am writing to this mailing list as I have not found any working solution online. We use the audit with ENRICHED log_format, but we see lots of parameters not being decoded from HEX, Here are the auditd settings: log_file = /var/log/audit/audit.log log_format = ENRICHED log_group = root priority_boost = 4 flush = incremental freq = 6000 num_logs = 10 disp_qos = lossy dispatcher = /sbin/audispd name_format = hostname max_log_file = 30 max_log_file_action = ROTATE space_left = 150 space_left_action = SYSLOG action_mail_acct = root admin_space_left = 100 admin_space_left_action = SUSPEND disk_full_action = SUSPEND disk_error_action = SUSPEND tcp_listen_queue = 5 tcp_max_per_addr = 1 tcp_client_max_idle = 0 enable_krb5 = no krb5_principal = auditd Installed audit Version: 2.6.5-3.el7_3.1 Here the problem parts of the Audit log (parameter a2): node=hostname.domain.tld type=EXECVE msg=audit(1500536092.301:232170298): argc=3 a0="/bin/sh" a1="-c" a2=2F7573722F6C6F63616C2F6E6167696F732F6C6962657865632F636865636B5F6E727065202D32202D482031302E3130302E3135302E313732202D702035363636202D6320436865636B46696C6573202D74203230202D6120706174683D463A2F636C656172696E672F6D6366742F706F736569646F6E2F206D61782D6469722D64657074683D30207061747465726E3D2A33335F303535305F4C5F2A2E434B38202266696C7465723D7772697474656E206C74202D33306D20414E442073697A652067742031306222204D6178437269743D31 not decoded parameter (a14) in the middle: node= hostname.domain.tld type=EXECVE msg=audit(1500536092.303:232170300): argc=16 a0="/usr/local/nagios/libexec/check_nrpe" a1="-2" a2="-H" a3="10.100.0.0" a4="-p" a5="5666" a6="-c" a7="CheckFiles" a8="-t" a9="20" a10="-a" a11="path=F:/clearing/mcft/poseidon/" a12="max-dir-depth=0" a13="pattern=*33_0550_L_*.CK8" a14=66696C7465723D7772697474656E206C74202D33306D20414E442073697A6520677420313062 a15="MaxCrit=1" We need ENRICHED log_formad so we can analyze audit logs on a central Log server. I tried to increase the „priority_boost“ parameter to 6, and increased the „freq“ param. to 6000 to give the auditd more time for decoding. None of the mentioned helped. What I don’t understand is that sometimes it’s the last parameters which is not decoded, and sometimes it one in the middle.
