Created attachment 287660 [details] Long UI Freeze exports from Error Log I constantly experience very long UI freezes while debugging. It seems to occur most often when eclipse stops at a (java) breakpoint in a method that is called from a lambda - in this case, the UI will almost always freeze for 50+ seconds before showing the call stack, variables, or even the class the breakpoint is in. After a fresh launch of eclipse, these breakpoints often work without UI freezes for some period of time (minutes or even hours). But the longer eclipse runs, the more prevalent and longer the UI freezes become. My eclipse.ini uses these memory settings: -Xms256m -Xmx2048m The freezes occur more frequently when the taskbar shows that eclipse is using more memory, but we're talking in the 800m+ range, not maxed out. I think this has been occurring for a long time, across several eclipse releases, and it's getting worse (freezes getting more frequent and longer with each release) I recreated my workspace from scratch a few months ago, but that made no difference. I'm running Linux Mint 19.3, fully patched, on a core i7-2600 with 32GB of system ram. I've exported a lot of entries from the Error Log (zipped, attached)
You seem to suffer from some webtools editor trying to show/maintain some annotations, probably lot of them. In general, I would suggest to increase your Eclipse heap to at least 4 GB, I would not recommend to use 2 GB in productive environment to anyone.

Upped Eclipses memory to 4096m, but it doesn't appear to have improved anything. eg taskbar shows current usage is "754M of 1440M". Restarted the app I'm debugging. Every step in the debugger takes many seconds (minimum). If I restart eclipse, stepping in the debugger takes no measurable time... for a while. >You seem to suffer from some webtools editor trying to show/maintain some annotations, probably lot of them. Any idea what, or how to stop it? I tried disabling folding, which resulted in no change. My source files aren't overly large, and only use standard @Override, and javadoc annotations.

Created attachment 288552 [details] stack dump Note that this might be related to having large XML file open in an editor (I had one open with 80k lines). Maybe somewhere around this? https://github.com/sandipchitale/eclipse.platform.text/commit/92de80af981bd304bdb21046e0ba5fb4bcf6080b
