Description:
When having the administration - Client connections view open for a long time on a busy server, workbench will use increasing amount of memory.

How to repeat:
1. Open administration - Client connections and keep it open
2. Run an import or other high number of queries that will show up in connections view.
3. Watch as the memory usage increases over time when the queries are running

Thank you for the bug report. I added 2 pictures: first one memory used while running a big query around 9 GB and the second one showing the memory was released by WorkBench after the query was finalized. So where is the memory leak?. Please check on your side too. Thanks.

I noticed it when connecting to a server over ssh but cant reproduce it when running against a local server

During an import the memory does not appear to go up when long-running queries like ALTER TABLE run, but goes up while INSERTs are running
