Log rotation issue

Run audit on dozens of systems but this one system (Red Hat 6.4 64 bit server Audit 2..2.2 ) does a strange thing. We use "/sbin/service auditd rotate" as part of a script that runs in /etc/cron.daily to do the audit extractions. When the /etc/audit/audit.log is rotated, all the entries in the log after rotation have their date as 12/31/1969 19:00. And on top of this there is a bunch of audit entries. Reviewing the log and the entries go along normally but when it does this date thing the log blows up in size. This is the same audit config I run on all the other RHEL 6 systems. My understanding is that when auditd rotates the logs that there should not be any further entries in the rotated log. Thoughts? David Flatley "To err is human.
