> 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
