I tried to activate all the presets in the preference menu. When i clicked “ok”, my software lags for around three minutes before an error occurs saying “JOSM is out of memory. Strange things may happen. Please restart JOSM with the -Xmx###M option, where ### is the number of MB assigned to JOSM (e.g. 256). Currently, 2010 MB are available to JOSM.”, and things went strange. Can someone help me fix this guys?
I think the NSI (Name Suggestion Index) is the worst preset ever. It really should be done via a different method (which doesn’t currently exist), and I have been forced to create workarounds for some issues that it exhibits (for example, on Mac, if you have the NSI enabled, you don’t get the menu bar in the standard Apple location, see JDK-8297117).
On the other hand, it is a great way to stress test the presets system.
With all that said, NSI makes it really easy to add common points of interest (McDonalds, WalMart, etc.) and have some confidence that the entries are “correct” (McDonalds or McDonald’s, WalMart or Wal-Mart, etc.).
Anyway, if you enable everything but the NSI, you will likely have a much better time on 2 GB ram.
Additionally, I suspect you are either on an old system (>10 years old), a new “cheap” system, or you are running a 32bit version of Java. If you are running a recent computer (<10 years old), you should look into installing the 64bit version of Java.
Notes on Java installation:
- JAR
- Install Azul Zula Java 21 (this is what we currently recommend)
- JNLP
- Install OpenWebStart
- You may have to uninstall Oracle Java 8 to get things working properly. I don’t think there are any “common” applications still requiring Java 8 and not working with Java 11+ (this includes Minecraft – they actually require Java 17+).
That’s a whole lot. Surely you’ve tried loading additional presets to see if single additions cause the same effect.
These are all the ones I’ve added, just not a dozen and they installed flawlessly, where Internal Preset is there out of the box.
This is the second time I’m reading about JOSM getting 2GB. Mine gets 4GB. Made no any command line hacks to achieve this. Maybe it’s because the machine has 16GB over the original 8. It rarely runs out of memory, it quickly grabs 3.8 and that stays. Never giving any back when unloading large data sets.
edit: With EasyPresets I make my own ‘custom’ presets, have advanced to #90 recently.
Did you give any follow up on this?
I personally start josm with:
java -Xms2048M -Xmx8192M -jar josm-tested.jar
I’ll bite, why not.
You haven’t indicated whether you tried the previously offered advice and whether it did anything. Without this information it is very hard troubleshoot this issue any further or to offer any new advice.
Additionally you also have a history of only ever adding fantasy projects (see this and this forum post) and seemingly not being able to understand the difference between real and not real. This makes people hesitant to offer their help.
The best way forward I think is remove all presets EXCEPT the Internal Preset and restart JOSM. Then add 1 preset at the time you selected, OK and verify the error does not occur. If it does not, add the next one, verify with OK. Repeat the process, 1 preset at the time until you get the error. It is important to OK at the bottom of the Preferences window after each selection.
I think Name Suggestion Index is a very big one that collapse JOSM.
Remove JOSM preferences file.
Yep, i just activated all the presets in my preference menu, and still receiving that error so it won’t do that. I guest can you please help me SekeRob or someone else?
@SekeRob Okay i tried that anyways, and it takes a very long time to do it. Is there another way to solve this problem sure?
Sure, i really want help now, is there another way to solve this problem anyone, reply?
@Thiskal Okay then Thiskal, but i need help because i activated a lot of presets in the preference menu, and when i clicked Ok button, suddenly after few seconds to minutes, an error appears saying “JOSM is out of memory. Strange things may happen. Please restart JOSM with the -Xmx###M option, where ### is the number of MB assigned to JOSM (e.g. 256). Currently, 2010 MB are available to JOSM,” and things started to go strange.
