Aureport on Centos 7 : Strange behavior

Hi, I came across a strange aureport behavior that would amount to a bug unless I am doing something wrong. I am on Centos 7.2 with : [root@odbfi021s ~]# rpm -qa|grep audit audit-libs-2.4.1-5.el7.x86_64 audit-2.4.1-5.el7.x86_64 If I run aureport -k --summary -ts yesterday 09:00 -te yesterday 10:00 I get the answer immediately. [root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:00 -te yesterday 10:00 Key Summary Report =========================== total key =========================== 409 log_IAM 27 IAM64 26 audit_log 23 open64 16 etc 1deletion Same thing with any round five minutes interval [root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:35 -te yesterday 09:40 Key Summary Report =========================== total key =========================== 1 IAM64 1 log_IAM [root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:40 -te yesterday 09:45 Key Summary Report =========================== total key =========================== 393 log_IAM 16 etc 11 audit_log 3 IAM64 2 open64 1 deletion But If I request a ten minutes interval or a five minutes interval not starting at zero or five aureport hangs !
