First of all i would highly recommend launching the game without the -maxmem=13 parameter. If the game crashes even after that parameter is deleted please attach newly generated dump files using these following steps.

Steps on how to export logs from ARMA 3 Launcher:

1. Start ARMA 3 Launcher
2. Click the Hamburger menu tab in the launcher (Top right corner. Next to Options (Cog wheel icon) and Minimize Button)
3. Drop down menu will appear
4. Select: Prepare Arma Troubleshooting error and save those files
5. A notification will pop up with the name of the generated file

Please note that the files might take a while to collect.

Attach the generated files to the ticket. If the files are too big please use some free file sharing service.
