Tracker could not be started due to OutOfMemoryError: Java heap space

4 Posts

Hey everyone,

all of a sudden I cannot open Tracker anymore. Everytime I try to, I receive an error message saying that an "out of memory error" occured, see the attached image.

I haven't changed anything about my system since the last time I used Tracker. Both Tracker and Java are updated to the latest version, although I tried Version 5.2 as well which didn't work either.

As the error message suggests, I tried opening tracker.jar which DID work in the beginning (although I could only close it again via task manager). I then tried around by setting the memory size to default and afterwards also to 4000. Since then I cannot even open tracker.jar anymore.

I reinstalled both Tracker and Java multiple times and restarted my computer (which runs on Windows 7, by the way).

Any suggestions?

Best regards

Well, I seem to have fixed it. I tried installing Tracker Version 5.1.5 which allowed me to open tracker.jar again. There I changed the memory size to default again and changed the Java Virtual Machine to the non-bundled one. Then I could open Tracker.exe again, so I uninstalled the old and installed the latest version (6.0) again, which now does launch properly.

I'm happy it's fixed, but I have no idea what happened. I was just randomly trying stuff out and had no idea what I was doing, so I would still like to know why the error occured in the first place and how to deal with it in the future. Cheers!
