mysql fatal error encountered during data read

[technolo_bi]

I am using a query that for a month give me sth like 700.000 rows with no big problems. When I am trying to get period of half year(it is around 4 millions rows) I got error "mysql fatal error encountered during data read". Is this because of my PC hardware and I need for example more RAM to deal with this huge amount of data?

@technolo_bi , there can be many reasons.

1. Increase timeout.

2, enable parallel loading in options and settings

3. increase memory for data management cache - under data load in options and settings

4. Increase virtual Ram of the system and make sure hard disk have free space

1. I have 1200 minutes timout and I got error after one hour.
2. I have enabled this option
3. I Increased my Ram from 2 GB to 16 GB but still got error.

4. I increased and there is a free space
Do you have any other advice please?
