  • mysqlbinlog oddness

    Getting some odd output when I run mysqlbinlog however it appears it is dumping the log file properly and aborting at the end.

    # mysqlbinlog mysql-bin.000233 > bin233.out

    Hi Grego,

    This looks more like a bug that was reported on windows build of MySQL 5.1 and was fixed in MySQL 5.1.17. I am not sure if that same bug is related to you. I will check out with the Percona Server developers and get back to you.

    Best,
    Ovais
