At times error logs are truncated from a controller
There is a limited number of records that can be stored in controllers and if there have been a lot of error they will eventually get truncated.
Flash memory for the controller error log is divided into 2 sections (A&B)
When section A is filled with errors, section B begins to get filled
Once both sections are filled, section A gets truncated and begins to fill with new records
Once section A is filled, section B gets truncated and so on...
There are approximately 8000-9000 records that can be stored in each section
