Hi Bohdar,
Thank you for your report, but we are going to need more information.
- Are you running any select queries that return a huge number of columns?
- What is your configured size of the Statements View history? (Preferences | SQL Editor | Statements)
- How much memory does your machine have?
- How large is your workspace folder? (C:\Users\*user*\AppData\Roaming\Dell\Toad for Apache Hadoop\1.5.1)
Regards,
Lukas
