OpenRoads Out of Memory Crashes

You're hitting the 32-bit application memory limit.  The limit for any 32-bit application is approximately 4 GB if programmed appropriately.  

This is the reason for the anticipation for the Connect Edition of OpenRoads...64 bit application which allows much more memory to be used.

Jaime, 

Did you figure out how to add the freelimit variable to the 32 bit version? I am unable to use a different software for a project but we have a basemap that keeps throwing the memory exception and cannot find instructions on adding the freelimit variable.

"I just tried adding the MS_MEMORY_FREELIMIT config variable (the one you may have been referring to) with 999Mb (max virtual memory free limit allowable) and it seems to actually be working"

That is a configuration variable that you can add to your user configuration file. It could possibly be incorporated at the project or site level, but I probably wouldn't do so because of possible variations in workstation computers.

If you go to the Workspace menu and select Configuration, you will get a dialog box listing the configuration variables. There is a button for "New" where you would add this variable, and enter the desired value. You will need to Save in the Configuration dialog before you close it, and you will need to exit and restart your program for the new value to take effect.

Hi Chris,

it is recommended to do not extend old discussion(s), but to ask in a new post. It ensures more attention and also allows to ask in current context (newer versions released in the meantime, Windows updated...).

Please follow the best practices and specify what product and version you use.

What exception exactly is reported? It is different whether it is reported by MicroStation itself (typically native code in V8i) or by NET runtime.

Did you search this web? There are several wiki pages about this topic, for example:

• General information about MicroStation V8 memory management
• How to allow lock pages in memory
• You can also find several discussions, where the variable was mentioned

I do not see any problem with this variable mentioned by Marc, you can add it to MicroStation workspace configuration or directly as Windows variable. But be aware it should always be used with other settings (like locking pages).

And it helps a little only, when NET memory exception is reported, because NET uses own memory allocation mechanism, which cannot be changed (code has to be compiled specifically).
