To reproduce: 1)Enable the undo.history.size property. It was initially set at 25 but even 5 was causing an issue 2)Open a relatively large JMX script (just opening the script is already slower when undo is active) 3)Carry out a search. If the script is large enough JMeter will consume all memory made available to it while trying to carry out the search and will freeze. Turning off the undo.history.size property and repeating the above steps after restarting JMeter shows much improved performance and does not freeze the application.
Could you provide the jmx script ?
