Simexe remain in memory after changin the model

[Richard P.]

Hi Brian,

I sent you an email on the issue, but wanted to post to the forum for anyone else who may be following the thread. We have fixed the issue and it will be available in a release coming out soon. For Windows users, it will require uninstalling existing 7.1.6 and installing the new version of 7.1.6.  I understand this is due to the way Windows maintains versioning for installed software.

Hi Richard,

As discussed in emails. The "fix" did not actually correct this issue. The issue remained with the updated version of 7.1.6 and the sample test case that was provided.

Any news on when a "fix" will be available? Possibly with the next major release dated ???

Thanks

Brian

Hi Brian,

I emailed the developer about it again, I will let you know when I hear from him. Did you install a file I gave you, or the one from the FTP site?

Has the build from Feb 6 2006.

Hi Brian,

I spoke to a developer, and we found that the memory is being fragmented by the system being killed and restarted. To make the build called 71mx3718 he used a tool called Purify to trace memory leaks using your model. He eliminated all of those memory leaksin 3718, but still observes the following: after 50,000 runs, the total memory in Windows went from 6MB up to 33MB. The total memory allocated, according to Purify, didn't change. This seems to point to memory fragmentation, which is expected from doing all the deallocation and reallocation involved.

Make sure you have 3718 installed, and notice that memory usage will creep up very slowly. But we aren't seeing any memory leaks anymore.
