Occasionally, an audit daemon dies while its audit file is still open, or a server becomes inaccessible and forces the machine to switch to a new server. In such instances, an audit file remains with the string not_terminated as the end-time, even though the file is no longer used for audit records. When you find such a file, you can manually verify that the file is no longer in use and clean it up by specifying the name of the file with the correct options.
# audit -s 19990414121112.not_terminated.egret # auditreduce -O egret 19990413120429.not_terminated.egret
The audit command checks the name of the current audit file. The auditreduce command creates a new audit file with the correct name and correct timestamps, with the correct suffix (egret), and copies all the records into it.
