truncated the error message. I found that there is more information in the actual mysql.log file had more info: InnoDB: which exceeds the log group capacity 9433498. InnoDB: If you are using innodb_fast_shutdown big BLOB or TEXT rows, you must set the InnoDB: combined size of log files at least 10 times bigger than the InnoDB: largest such row. So, as it seems, the InnoDB log file settings need to be updated. I found a listing of the steps to takeon MySQL's website. Here are those steps fleshed out a little. 1) Make sure yourinnodb_fast_shutdownsettings is not 2.To innodb error log file ib_logfile0 is of different size fix this, set it to one by runnning the following query: SET GLOBAL innodb_fast_shutdown = 1; 2) Shut down mysql and look for errors in the log to make sure nothing went wrong. service mysqld stopcat /var/log/mysql.log 3) Copy the old log files to a new place in case something goes wrong. mv /var/lib/mysql/ib_logfile* .. 4) Next edit your /etc/my.cnf file to increase your InnoDB log size: innodb_log_file_size=128M You may see people suggesting really large values for the log file size -- I saw a value of 768M in one StackOverflow answer. If that seems like a suspiciously large, random value to you (especially considering the default is 5M) then you're on to something. But that begs the question, what should the value be? Here is a helpful article on how to properly size your log files. 5) Lastly, watch your /var/log/mysql.log file and start MySQL back up. service mysqld start One helpful tip, if you see this error in your log file, /usr/libexec/mysqld: Incorrect information in file: './schema_name/table_name.frm' then you probably tried to skip step 3, like I did. Turns out, this is an important step and your MySQL s

More specifically I don't http://serverfault.com/questions/293406/mysql-innodb-error-the-age-of-the-last-checkpoint-is-x-which-exceeds-the-log understand how the age of the checkpoint relates to the "log group capacity", and how that in turn relates to the size of rows with large BLOB/TEXT columns.

To solve it, you need to stop MySQL cleanly (very important), delete the existing InnoDB log files (probably lb_logfile* in your MySQL data directory, unless you've moved them), then adjust the innodb_log_file_size to suit your needs, and then start MySQL again. This article from the MySQL performance blog might be instructive. share|improve this answer answered Jul 23 '11 at 23:40 womble♦ 76.7k11117184 1 What are the consequences of just ignoring the error messages? –Matt Healy Jul 24 '11 at 2:23 1 You're joking, right?

Also affects distribution/package Nominate for series Bug Description I have a server running Debian 6 (Squeeze) and Percona 5.5. Logs indicate that for a while, there's been a warning that: 150202 22:19:18 InnoDB: ERROR: the age of the last checkpoint is 9448357, InnoDB: which exceeds the log group capacity 9433498. InnoDB: If you are using big BLOB or TEXT rows, you must set the InnoDB: combined size of log files at least 10 times bigger than the InnoDB: largest such row. I am aware of what this means and that the innodb_log_buffer_size needs to be increased. Unfortunately no-one had noticed this alert on this server :/ But since the upgrade to 5.5.41-rel37.0-727.squeeze, eventually these error alerts in the log seem to culminate in a giant MySQL crash, which didn't used to happen. These lines, for example, appear right after the last checkpoint alert as above (but there had been many preceding it): 150202 22:19:18 InnoDB: Assertion failure in thread 1420909424 in file sync0rw.c line 569 InnoDB: Failing assertion: !lock->recursive InnoDB: We intentionally generate a memory trap. A full output of the log is attached (from the last checkpoint error, and onward). The corruption appeared to fix itself on this occasion (without anyone even noticing), but the next day it occurred a
