Dremio ODBC Driver 1.5.1 Release Notes
The following issue has been resolved in Dremio ODBC Driver 1.5.1.
If the Drill server becomes unavailable while a connection is active, the driver reports the error “ Synchronous socket write failed with error: An established connection was aborted by the software in your host machine.”, even when the server becomes available again.
This issue has been resolved. The driver now correctly updates the SQL_ATTR_CONNECTION_DEAD property and evicts stale connections from the connection pool.
