Hi, I am not a newcomer, but I didn't find a specific forum for this question.
My Eclipse frequently freezes for several seconds, usually longer than 20 seconds. Such a freeze happens 5 to 10 times an hour, or even more.
The workspace log then contains messages like this:
!MESSAGE UI freeze of 21s at 14:17:52.800
...followed by a long thread dump. All threads are either RUNNABLE, WAITING or TIMED_WAITING, i.e. none is actually running, if I am not wrong.
I don't do anything in particular when a freeze happens; I feel that copying text in an editor might trigger it, but then again I do it all the time so I may be wrong. Restarting Eclipse doesn't seem to help.
I have used Eclipse for a long time, and I have learned that an occasional freeze is nothing to worry about, but this new behavior is really annoying.
I use Eclipse 2023-12 with Adoptium Java 17 on Ubuntu 22.04.4 LTS with Gnome in a VMWare Horizon desktop. Any of these components might contribute to the problem, but only Eclipse is affected, no other program.
I could file a bug report, but first I'd like to collect more evidence. What are likely reasons for a freeze, and where can I find more information, error logs, load metrics and the like?
