up and rise to the top Error reading MySQL 5.5 binary log using mysqlbinlog up vote 1 down vote favorite I'm having some trouble with a replication setup I'm using. It has been working fine for months, and then over the weekend, the slave stopped reading updates from the masters binlog with an error Got fatal error 1236 from master when reading data from binary log: 'bogus data in log event' When trying to read mysql error log format the relevant binary log using mysqlbinlog, I get the error shown below; [root@slglcd-01] # mysqlbinlog ibm-pr-slglcd-01.000075 > /dev/null ERROR: Error in Log_event::read_log_event(): 'Event too small', data_len: 0, event_type: 0 ERROR: Could not read entry at offset 1828: Error in log format or read error. [root@slglcd-01] # Frustrating! I have tried using various combinations of --start-position and --offset to try and get past the bad data, and nothing seems to be working... What I'm after is a way of skipping (or removing) this error from within the binary log, creating a new binary log without the offending item, so that I can continue my replication. I'm not worried about loosing the statement, this is a syslog collection database, and one missing row isn't going to hurt. What I can't do is re-create the slave from the master, as the master uses the BLACKHOLE engine, and therefore has no real data stored... If the worst comes to the worst, I will have to start from the next binary log in the sequence and loose the data left in the offending log.

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.

Reimage also restores compromised system settings and registry values to their default Microsoft settings. You may always return your system to its pre-repair condition.
