Error analyzing java application using Intel Inspector on Linux

Hi,

I have successfully used Intel Inspector to track down memory leaks on a Windows server machine. When I do the same on Linux I get the following output and the application does not even start:

Note that I have also tried to analyze a simple Hello World like Java application, it results in the same error. I suppose that the extensive use of signals of the JVM is causing problems. Using the JVM option -Xrs did not help. Note that analysis works perfectly on Windows.

Any help / suggestions are highly welcome!

Hi, 


Thank you for the feedback.


Unfortunately, the Intel Inspector tool doesn't support Java officially on Linux and Windows.

The issue is how to find memory leakage on Java programs, for that you may have to look out for other options available in the industry.

Sorry for the inconvenience caused.


Also can you please confirm whether we can go forward and close this case?


If this resolves your issue, make sure to accept this as a solution. 

This would help others with similar issue. Thank you!


Thanks and Regards, 

Diya

Hi, 


Thank you for posting in Intel Communities.


Could you please share the following details- 


1. Sample reproducer code and the exact steps to reproduce.


2. Intel Inspector version.


3. Kernel Version.


4. OS and Processor details.


Thanks and regards,

Diya

Hi Diya,

Steps to reproduce:

* Install Java if not yet done

* Create file Hello.java containing the following content: class Hello {  public static void main(String[] ignored) { System.out.println("Hello"); } }

* Compile it using javac Hello.java

* Run it without inspector, it should print "Hello" on the console: java Hello

* Now run it with the inspector: /opt/intel/oneapi/inspector/latest/bin64/inspxe-cl -collect mi1 -knob detect-leaks-on-exit=true -- /usr/bin/java Hello

--> In my case it results in a message Run terminated abnormally. Some data may be lost.

 

Intel Inspector version is 2023.0 (build 606330)

OS is Ubuntu 20.04.1 kernel version is 5.15.0-1028-aws

CPU is Intel Xeon Platinum 8259CL.

 

Let me know if you need additional data.

 

Thanks and have a great weekend!

Marc

Hi, 


Good day to you.

We were able to reproduce the issue from our end.

Actually, Intel Inspector has certain application coding requirements.

It supports the following programming languages:

C

C++

Fortran

So, please try Intel Inspector for applications with the above-supported languages.

You can find it in the release notes of Intel® Inspector 2023.0: https://www.intel.com/content/www/us/en/developer/articles/release-notes/inspector-release-notes.html

If this resolves your issue, make sure to accept this as a solution. 

This would help others with similar issues. Thank you!


Thanks and regards,

Diya

Hello Diya,

Thanks for your message. But why does the tool work just fine on Windows? This is a major limitation from my POV since it means that you cannot use the tool on Linux to analyse memory leaks for applications that use a Java VM and JNI.

For me it means that I have to run the application on a Windows server. Unfortunately the leak is not reproducible on Windows. I am going to use /proc/PID/smaps now to identify leak candidates but this is a messy task especially when the content of the memory allocations contains just binary stuff that cannot easily be matched with lines in your code base.

Best greetings from Germany,

Marc

I have accepted your answer but I still believe there are options for a fix on your end since the tool works fine with JVMs running on Windows.

 

Best regards,

Marc

Thanks for the confirmation. 

We are closing this case as of now.

If you need any additional information, please post a new question as this thread will no longer be monitored by Intel.
