#2834 new defect
GUI might freeze when downloading multiple Hive jobs concurrently

Description
I ran into what seems to be a GUI deadlock today while I was downloading Jobs from the Hive Server (multiple downloads concurrently).
The threads stopped in the following methods:
- HeuristicLab.Clients.Hive.JobManager.Views.RefreshableHiveJobView.OnContentChanged
- HeuristicLab.MainForm.WindowsForms.AsynchronousContentView.Invoke
- System.Windows.Forms.Control.WaitForWaitHandle
The GUI froze but execution of algorithms in the background was not affected.
RefreshableHiveJobView.OnContentChanged contains a lock() statement. The code in OptimizerHiveTask contains operations with ReaderWriterLocks. I presume the observed behavior can be traced back to these methods.

tickets.
I would suggest to move this to 3.3.17. As a workaround, download all jobs in sequence.
