OutOfMemory Error - How to Set Xmx/Xms Values

[franmotta]

Hello, I need to improve the memory usage of the program. What value you originally set to Xmx/Xms of the ExpertLotto? I'm using a Mac Pro with 32GB of memory, but the program is still returning the "OutOfMemory error". Where can I change the Xmx and Xms of the ExpertLotto to set a higher value?

THANKS,
Fran Motta

I need to configure the following items: XXMaxPermSize, -Xms, -Xmx

THANKS!

Are the following information the limits [Minimum and Maximum] of memory usage by the program?

###################################################
Heap memory usage: initial 32,0MB maximum 123,9MB
Non heap memory usage: initial 23,2MB maximum 130,0MB
###################################################

Thanks, Moti... I'll take a look!

I did as taught on the link and got the following error:

Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified

Can anyone help me? THANKS!

Just fix it! I just added the following command "-Xmx1g" [no quotes] in the file "expertlotto.conf".

So to help users who may have the same problem in the future, I leave here a small tutorial:

NOTE: To change the Xmx value, you must have Java 64bit installed. It is also recommended to use a specific editor for programming language (I used TextWrangler - MacOSX), because a common text editor can generate an error in the original formation of the file "expertlotto.conf", which is essentially a Java file.

STEP BY STEP
1. Open the file expertlotto.conf using the "open with" (in this step, choose open with text editor);
2. On the line that appears - "branding expertlotto-J-Xms32m" - change the Xms value to a Xmx value (never exceed 50% of your memory capacity). In my case, I changed "-J-Xms32m" to "-J-Xmx1g"
3. For me it worked like a charm!
4. The attached picture is just to show the line that needs to be edited.

Nice tutorial, thanks!
But you can leave the Xms option untouched. Just change/add -J-Xmx option to adjust the maximum available RAM.
And also keep in mind that you need 64 bit Java runtime if you want to allocate more than 800Mb of RAM for the application, otherwise the application may fail to start.

I have about the same problem, although I have changed Xms32m to Xmx2g.

The application makes the statistical analysis (ticket analyzer, 76 latest draws of a 6/45 lotto) and then it gives me the results with a pop up "out of memory".
Is the statistical analysis ok or not ?
The same happens when I run a complex filter. The application filters the ticket package, it gives me the results with a pop up "out of memory".
Are the results ok or not?

I have 6GB RAM

Thanks in advance

Please email me your application log. Either you've adjusted your memory settings wrong or you are running some stats that just need a lot of RAM (for example when playing with many History levels).

Hi Stan

I'm running EL 5.8 and have 4 GB RAM. I recently upgraded to Windows 10 and EL is now running very slowly when filtering only a few thousand (e.g. 60,000) tickets whereas previously the same filter would run much quicker. In the application log I got the following warning messages:

WARNING [org.netbeans.modules.openide.filesystems.declmime.MIMEResolverImpl]: Ineffective registration of resolver Services/MIMEResolver/ComplexFilterResolver.xml use @MIMEResolver.Registration! See bug #191777.

Also, here is another extract from the log showing the memory parameters:

I have tried to increase the memory available to EL but I was unable to edit the config file using Windows Notepad - I got an 'Access denied' message.

Can you assist please?

The slow processing could be related to antivirus scanning - Expert Lotto does a lot of I/O operation during filtering so your antivirus might a bit too aggressive.
To edit the config file you need to open Notepad as administrator to get appropriate privileges - right-click the Notepad icon in Start menu and choose 'Run as administrator'
