I see this error in mysql.log:
InnoDb error: the age of last checkpoint is...which exceeds the log group capacity etc..
I think I understand it, but the fact is that it's happening only during a night operation at minimum load, consisting in a 100MB db import.
I import the result of
mysqldump --opt, with the purpose of duplicating a db for testing.
The error suggests an increase in the log file x 10 times.
Considering that in no way I'm reaching this limit during normal daily time, I wonder if there is another way of dealing with the problem, rather than changing the log file size and restarting mysql...
The speed of the import operation is not important.
