Problem allocating enough memory to Java heap #10797

Closed Betcsdad closed 2 years ago

Betcsdad commented 2 years ago

I can’t get my 64 bit Windows 7 computer with 8gb of main memory to allocate more than 270 meg of Java heap space.

This machine is running JMRI version 4.26 with the 64 bit version of Java 11.

PS my other Windows 7 laptop is a 32 bit machine and it allocates over 900 meg to the Java heap space. It is running JMRI 4.26 and the 32 bit version of Java 11

On my 64 bit Windows 7 computer with 4 GB of memory I get 1988 megabytes heap size (see below).

There is nothing special on Windows system start in my case. Open a CMD window to run msconfig and to see what Windows is loading at system start in your case. Please compare your both computers. This could be a clue.

with the 64 bit version of Java 11.

This is insufficient information to define a particular JAVA vendor's JAVA Runtime Environment release. Java implementations are provided by a number of vendors, and the release number can be a critical piece in debugging JAVA issues.

Thank you for the response. I’m going to be out of town for a couple days and won’t be able to access the computer again until Friday.

I’m sorry I forgot to include that it was Java version 11.0.14 from AZUL . I noticed it now says 11.0.14.1+1

If you run the LaunchJMRI.exe file (the usual launcher) with the /debug switch it will provide additional information about what it's doing. Not a windows expert, not sure how to do that.

klk32003 commented 2 years ago

See https://www.jmri.org/install/WindowsNew.shtml#startupissues how to run the LaunchJMRI.exe file (the usual launcher) with the /debug switch.

Betcsdad commented 2 years ago

It appears some of my responses to the emails haven't made it here. I have removed programs from the startup list, uninstalled the Azul version of Java and installed the Oracle version, etc. but the script never shows more than 260 megs of heap space.

Here's the info and activating the debug switch

That’s really odd.

The "-Xms96m -Xmx1997m “ options say that JMRI is telling Java to provide a minimum of 96MB memory, and allow the memory usage to go up to 1997MB. That’s all that the JMRI startup can say. There must be something else, other than JMRI’s startup, that’s limiting how much Java can allocate.

Do you have a global JAVA_OPTS or _JAVA_OPTS set?

Says it might be a 32-bit java issue. Are you running java as 32 bit or 64 bit? Apparently 64bit works better with large physical memory

Thank you. I went looking in “environment variables” and found a max of 256 meg had been set. I deleted the line, restarted and now have 1998 meg allocated to. A max heap size.

Not sure how or who set that up, but it’s gone now

Thanks again,

@Betcsdad Good to hear you've found the cause and solved it. There had to be something specific to your installation.

Betcsdad commented 2 years ago

I did the initial Java and JMRI installation on this laptop years ago. I have no idea how a fixed maximum heap size would have been set, but I’m glad it’s working now

Betcsdad commented 1 year ago

I am currently running the 64 bit version of Java from Azul. I’m not sure how to set a global Java anything 😉
