NX 7.5 memory access violation error.
NX 7.5 memory access violation error.
(OP)
Hi Guys,
I don't know if anyone else has had this problem before, but one of my users is telling me that whenever he opens either a model or drawing from Teamcenter (We are using TC 8.3 + NX 7.5) he consistently gets a memory access violation error (see attached picture).
He also states, that if he gets this error while he is busy working with a model, then he is unable to save any progress he has made since his last succesful save and therfore loses all his changes.
His computer is a:
- HP Z400 Workstation
- Windows XP 64 bit
- 6 Gig. RAM
- 3 GHz Xeon Quad core CPU
- nVidia Quadro FX 1800 GPU
I am currently downloading the 7.5.4 MP & MR patch which i hope will sort this problem out, but i could be wrong. Any thoughts?
Thanks in advance!

occurs this problem after the last NX 7.5.4 update?

Yes, x64 version of NX is installed.

If so, what is this file, what is it's function?
Thanks!
RE: NX 7.5 memory access violation error.
Note that this feature can be disabled so that these settings are NOT remembered from session to session, that is, they're reset once you close your current NX session and your next session will revert the Customer Default settings. However, the out-of-the-box default is to retain these settings from session to session, thus the creation and use of the 'DialogMemory.dlx' file.

I've just deleted a 52MB dialog memory file.

Case in point, I just checked my dialog memory file for NX 8.0. I installed my first copy of an early development phase back in September, 2010, 11 months ago, and the first time you launch a new system this .dlx file is one of the first files created by the system and unless you explicitly delete it, it will continue to be reused and even as I de-installed old versions of NX 8.0 and installed new ones, this file, as well as the other files in the ...\appdata\local\unigraphics solutions\NX80 folder are not replaced, but simply accessed and are continued to be used. Anyway, in 11 months, my NX 8.0 .dlx file isn't even up to 5MB yet. Now granted, I'm not running NX 8.0 in a production environment, but it has been 11 MONTHS and I've done a lot of testing and many many demos, and it's only up to close to 5MB.

Also seen where NX will not start at all. Delete the dlx and it can start again. As I said this has been seen on a number of different systems.

That file can get quite big, quite quickly, for CAM users. It can then cause a multitude of issues.
The response from GTAC for our CAM users in Brazil was to switch to a 64bit OS. Deleting the dialog memory file cured the problem.

Toggle off Save Dialog Box Settings between Sessions
This should keep the file size in check.
