      Description

      Referring to Microsoft bug report https://support.microsoft.com/en-nz/help/177199/bug-readeventlog-fails-with-error-87the Agent should use different API method.

      Additional information:

      If the log file is 2MB or larger, the seek method of reading the event log will fail to read the earlier records in the file. For example, expect ReadEventLog to fail when reading records with the dwRecordOffset parameter set to 1 or 2 or maybe 11 or 12, depending on how full the log file is. ReadEventLog may continue to succeed and work properly for seeking to later records, for example dwRecordOffset set to 100 or 200.

      Resolution:

      The calling application should not use the EVENTLOG_SEEK_READ flag with ReadEventLog if the size of the event log file is not determined. Instead, use the EVENTLOG_SEQUENTIAL_READ flag and use repeated calls to ReadEventLog to implement code to scan to the record of interest.
