Out of memory error while starting NWDS

[Former Member]

Hi.

I have NWDS 7.0.08 installed. I'm developing DC's assigned to a DTR. While working, I had about 10 projects open in the workspace and when I tried opening another one, NWDS crashed giving an "out of memory" error. And when I try to reopen NWDS, I get the error "Problems during startup. Check the .log file in the .metadata directory of your workspace".

When I look at the log, I see the following lines:

I cut off some parts as they are too long and seem to be useless.

I guess NWDS is trying to reopen the projects I was working on while it crashed. So, how can I prevent it?

I can't change my workspace because I have open activites in DTR, so I shouldn't loose my DCs.

Help? Anybody?

Thanks in advance..

Hi Mehmet,

make a backup of your workspace folder and after try to delete the workspace folder and restart the NWDS.

Hope this help

Hi Francesco.

Thanks for your answer, but it's no use for me. If I delete my workspace, NWDS opens normally, but with a fresh interface. I can't see my old projects. As they are DC projects bound to NWDI, and I have checked out some of them, I don't want to lose them. I have to get my workspace back.

Hi guys.

I've solved my problem. I deleted the project navigator tree structure files from workspace, and NWDS opened up with a clean workspace . But the projects themselves were there though. So I recreated my DC projects, but didn't download the sources, modified local copies are used instead.

I deleted the these files:

<workspace>\.metadata\.plugins\org.eclipse.core.resources\.safetable\org.eclipse.core.resources

<workspace>\.metadata\.plugins\org.eclipse.core.resources\.root\###.tree

Then I opened NWDS and it was clean. I opened the Development Configurations perspective, in the Local DCs view, right-clicked on each DC and choosed "Create Project". This looks like a safe method, it worked for me.
