Log Event Entry Exceeded Max_allowed_packet

best answers are voted up and rise to the top Looking for an efficient way to fix “Could not parse relay log event entry…” error up vote 3 down vote favorite 1 I have a corrupt relay log in MySQL 5.0 and looking for the steps to fix replication without having to reprocess all the binary logs from the master again. Here is the full error message if you are curious: Could not mysql relay log corrupted parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. The normal fix is quite easy, you just obtain the correct binary log name and position from show slave status and run the change master command. But this is not what I would like to do. I would like to reprocess only one or few binary logs from the master to recover the corrupted relay log and then continue to use the relay logs that were already created. I am looking for someone who had past experience doing this as there is a potential for failures doing the recovery this way. Conceptually, I am thinking the following steps might be needed (maybe some of them are optional): Stop replication on the slave. Shutdown slave instance. Move relay logs to a safe location. See if relay-log.info or master.info files need to be

We're trying to set up MySQL replication using one slave. The slave appears to be replicating fine, and relay log read then the following error occurs: Could not parse relay log event entry. The possible reasons are: the master's binary log is corrupted (you can check this by running 'mysqlbinlog' on the binary log), the slave's relay log is corrupted (you can check this by running 'mysqlbinlog' on the relay log), a network problem, or a bug in the master's or slave's MySQL code. If you want to check the master's binary log or slave's relay log, you will be able to know their names by issuing 'SHOW SLAVE STATUS' on this slave. In order to benefit the large number of people who will inevitably stumble upon this question from a search, it would be helpful if someone who responds provided an overview of what could be going wrong and what steps to take to resolve this issue, but I will also provide more details below related to my particular situation in hopes that someone can help me solve it. The dump that we imported into the slave to get it started was created using the following command on the master: mysqldump --opt --allow-keywords -q -uroot -ppassword dbname > E:\Backups\dbname.sql The script that performs this backup also
