Aki Yoshida commented on CXF-4867:
----------------------------------
Hi Ulrich,
I don't have a CRM 2011 test system and a test program should run locally,
otherwise we cannot look at the problem. If you can modify your program into a
unit test that runs against a mocked local service using the same security
setting, I can modify it (e.g., just adjusting the security setting) to run it
in my environment.
Regarding the potential memory issue in ws-security, at least I didn't see any
memory build up, when I executed our spnego ws-security test case for multiple
times (20000 times).
As I mentioned in my previous comment, you should look at the objects that are
holding those string and xml attributes in the heap (see my previous reply). In
addition, maybe you can put your heap file somewhere accessible.
regards, aki

> Hi there!
> I have written a test program that reads entities from a Microsoft Dynamics
> CRM 2011 using CXF 2.7.3. The program was compiled and run as a runnable jar
> with Java 1.6.0_37 (32 bit).
> Now, when I run the program (in my case with the command line 'java.exe
> -Xmx1600m -jar TestCXF.jar contact 2013-02-25') and look at the memory usage,
> I do not understand why it needs so much memory (about 1.6 GB) for only 4 *
> 3099 records, even though the records are minimal (no attributes). The
> consequence is that when I have to read more records (e. g. the target CRM
> has more than 50'000 contacts), I will get an OutOfMemoryError.
> Furthermore, the test program finishes after four loops and releases its
> memory. The actual productive program on the other hand is meant to run for
> hours, so it would be very helpful to know how to free the memory, but
> calling System.gc() or re-connecting to the CRM did not work.
> Do you perhaps have an explanation for this behavior and can you give me a
> hint how to lower the memory usage?
> I have attached two screen-shots and a zip file with the runnable jar and the
> main source files. If you need any further information please do not hesitate
> to send a mail.
> Thank you and kind regards
> Ulrich
