I am trying to import a fairly large and complex ERwin model into IDA 7.5.3 using the Data Model Import function. The Erwin version is 7.x and I followed the instructions in the bridge, saving the file as an XML format and running the import. With smaller models I have successfully imported without issues, but this one just doesn't seem to work no matter what I do.
The curious part is it's clearly not hardware limitations, I have monitored the memory usage on the machine during the import process and it tops out around 30%, nowhere near any danger zones I've experienced before with memory leak issues. Has anyone run into any similar issues or have any suggestions on something to try? Thanks in advance for any assistance!
Here's the snippet from the import log showing the error I receive:

Re: Out of Memory Error on Model Import2012-12-07T19:20:03Z in response to rraddatzHi Robin,
Thanks for your reply, unfortunately I think the full model probably has proprietary information in it which would make it difficult to share in a public forum. If you have questions about the model size or anything I'd be happy to share those with you.
I am currently trying to experiment with the memory parameters in the .ini file for IDA to see if that allows me to get around the issue, but if there are any other ideas I would appreciate it.

Re: Out of Memory Error on Model Import2012-12-10T18:47:12Z in response to SystemAdminHi,
If you are a paid IBM customer, please email me and we can discuss proprietary agreements concerning sharing your model.
In the meantime, did you try something like this to increase your memory for MITI (tool used to import model). Not sure what version you are using, but you can
change file MIRSetup.xml (by default, it's located in C:\Program Files\IBM\sdpshared\plugins\com.ibm.datatools.metadata.wizards.miti.win32_xxx\MetaIntegration\conf). Change the value in the <options> element, as specified below:
Purpose: Java Run Time Environment (JRE or JDK)
Purpose: JRE or JDK Executable
Value: Executable Full Path (Optional)
e.g. javaw or java in debug mode
Default: <Meta Integration Home>\jre\bin\javaw.exe
Win32 e.g. C:\Program Files\Meta Integration\jre\bin\javaw.exe
Win32 e.g. ..\..\jre\bin\javaw.exe
Unix e.g. /usr/MetaIntegration/jre/bin/java
Purpose: JRE or JDK execution Options
Value: Run time option string (optional)
Default: "-Xmx256m" to allocate more memory
<Options>-Xmx1024m</Options> *** - this is the option I'm talking about
Re: Out of Memory Error on Model Import2012-12-10T19:40:45Z in response to rraddatzHi Robin,
That worked great! I added the option you mentioned to the .xml file and the model imported without hitting the out of memory issue. Thanks for the help!
