> I tried to reproduce the problem with local MySQL and PostgreSQL but couldn't. The problem can be reproduced only when using remote MySQL and PostgreSQL. On my local machine the error appears with limit more than 200000 rows, on another machines the exception appeared when setting limit 400000 and more. It seems it's related maybe somehow with MySQL timeouts or network delays. If I copy the table from remote MySQL to local PostgeSQL the error doesn't appear, and vice versa, if I copy the table from local MySQL to remote PostgreSQL the error doesn't appear again. I don't have an access to the remote MySQL to have a look at its internal options. I also tried to set net_write_timeout=1800 jdbc property for data source of the remote MySQL, tcpKeepAlive=true, tried to set ThreadBound MySQL translator property to true value - it didn't help at all. What do you think, is it possible to avoid the error on Teiid level?
> I also attached a server log with org.teiid.CONNECTOR and org.teiid.PROCESSOR log outputs.
