I'm on MacOs 10.13.4 (High Sierra)
Using IntelliJ 2020.3.1 (Community Edition)
I've tried increasing the heap size but failed. I've tried these two things:
Changing through the dialog box Help->Change Memory Settings. But I get stuck with the spinning cursor and have to force quit IntelliJ. However when I restart IntelliJ the memory is increased. But when I run something that requires a lot of heap size I get "OutOfMemoryError: Java heap space".
Changing directly in the idea.vmoptions file. Changing "-Xmx750m" to e.g. "-Xmx8096m". But after restart of IntelliJ I still get: "OutOfMemoryError: Java heap space".
IntelliJ->Help->Edit Custom VM Options...
I have run the exact same files in Eclipse after increasing the heap size there to 4096 mb. Therefore I know the problem isn't that the program I run need more heap space than that. To me it seems like there's no effect from the increase.
Hope you guys can help me!
You can try the following:
File->Settings->Build,Execution,Deployment->Compiler->Shared build process heap size (Mbytes)

I have a problem compiling FMU's in Jmodelica. for a medium size model I get the following error.
I already chanded the runtime parameter of JAVA in control panel and also tired setting the JVM allocated memory as high as possible using Xmx command. I'm running it on a pc with 128GB RAM.
Does anyone know how can I solve this issue in Jmodelica?
The JVM that is being used from JModelica does not take into account the system settings for the JAVA runtime parameter. You'll need to set it in the compile_fmu command. I.e.
compile_fmu(...., jvm_args="-Xmx10g")
I'm unable to increase the memory for the app, and app keeps its default 1Gb of heap.
Seems the settings in SpringToolSuite4.ini (what used to be STS.ini) are being ignored.
Putting the "-Xmx" configuration BEFORE the "-startup" seems to resolve the problem.
I've seen a few people encounter this issue with the heap size, which seems to be the issue in my case:
2> Could not reserve enough space for 1048576KB object heap (TaskId:336)
I tried manually setting it to 1G:
Got the same error, realised the space required is actually greater than 1G (it's about 1.04GB), so I set it to 2G. But this just escalated the error:
1> Could not reserve enough space for 2097152KB object heap (TaskId:305)
I thought I'd go nuclear and just set it to 10G, but then I got a different error saying it failed to create the Java VM.
In all honesty, I don't actually know what these mean, I'm just following along based on research of other SO and Xamarin Forums posts. Can anyone explain to me why I'm seeing these errors and how I can fix them?
Notes based on other questions: It's on debug, not release, and I don't have ProGuard ticked.
Steps to fix:
Select 64-bit Java SDK (as per instructions)
Set heap size to 5G (as per screenshot in question)
Built and ran successfully after this.
I'm using Windows 2012 R2 machine.
I have set my Heap Size in Environment variable as follows
ES_HEAP_SIZE
4g
After setting the heap size, i have installed Elasticsearch as windows service using command
service.bat install
When i started the service, Elasticsearch services has taken 4GB properly (Checked in Taskmanger.exe)
After some time, the memory used by elasticsearch service is came down to 1 GB.
Is this expected?
This is apparently an issue of ES under Windows.
Quoting from the link:
The 4gb committed heap size that you see in the node stats API is the amount of virtual memory that's reserved by setting ES_HEAP_SIZE (Xms), which is expected, even with bootstrap.mlockall disabled.
By enabling bootstrap.mlockall, we expect the call to VirtualLock() to lock the working set into physical memory, which happens initially (this is the memory you see in task manager), but eventually drops off.
I don't have a solid explanation for this yet, but I have observed that the more memory pressure the system is under (i.e. less free space available), the quicker the "drop off" occurs. It's as though Windows doesn't respect the fact that the pages in the working set are locked, and will release them when resources become low.
There's a lot of info out there that seems to indicate that VirtualLock doesn't guarantee pages won't be swapped, only reduces the odds, however the documentation says nothing about this.
1Gb is default heap size for Elasticsearch. So when you set the env.variable, you set maximum amount of memory it's allowed to use. If you don't issue any queries, the memory usage may drop to the default
On launching Jmeter, getting below error:
Error occurred during initialization of VM Could not reserve enough space for object heap errorlevel=1.
Please help me to resolve this. I am using laptop with 4GB RAM, 64-bit OS, intel i-5 core.
There could be a lot of processes running in your laptop. That is why you get this error.
Stop all the unwanted programs.
Check the HEAP size setting in JMeter.bat file. Reduce it (128, 512, 1024..)
You need to do the following.
Go to JMETER_HOME/bin folder
Open "jmeter.bat" (assuming you are using windows)
Check "set HEAP=-Xms512m -Xmx512m" (check the heap size- change accordingly)
Update, Close and Relaunch JMeter
You might need more heap for simulating more load.
