[2.0.0b2] 1.5 projects with ethernet switch may fail to open and GUI crashes

[dmfigol]

Hi!
I have crashed a GUI with a project which was working fine on 1.5. The project is replica of INE topology: 20 L3 IOL + 4 L2 IOL connected to one Ethernet switch. When I am trying to open this project in 2.0 the following happens:

1. Load is extremely slow
2. Later the following error is observed and the project does not open:
3. GNS3 crashes in 50% cases.
   It seems that it caused by the fact that Ethernet Switch in my topology has more than 20 ports.
   Please be aware that in the attached topology file I put placeholders "PUT-L3-IOU-NAME-HERE" and "PUT-L2-IOU-NAME-HERE" instead of actual image names.

   Error:

Do you have the project before conversion to 2.0?

Hi Julien, I think an attached project is from 1.5.x, is it not? If not, how can I check if it is converted or not? Most likely I have what you need, since I store gns3 projects in dropbox.

Oh you are right

Ok should be fixed in this build https://sourceforge.net/projects/gns-3/files/Nightly%20Builds/2017-01-23/2.0/GNS3%20nightly-2.0.0dev8.dmg/download

Thanks for the help
