Mysql 5.6 INNODB losing days of data

[Jonathan Angeli Paçoca]

I work at a software company, and used as database Mysql 5.6

Problem: In recent days MYSQL has losing days of data, like a big rollback of datas in all tables, checking the MYSQL error log, only appears the follows messages: "database was not shutdown normally" and "[Note] InnoDB: The log sequence numbers 1181074230 and 1181074230 in ibdata files do not match the log sequence number 1181075227 in the ib_logfiles ".

These messages could be related to the problem of data return days ago? May be some setting in my.ini is not recording transactional data? I never had this problem in MySQL 5.1, could it be a Mysql 5.6 bug?

The my.ini:
