Windows : DS9 fails to display or script fails to get box coordinates.
Make sure the path to the Owl DS9 directory is in your PATH environment variable. Also, you may need administrator privilages for the display to function.
Windows : Application crashes when accessing image buffer (i.e. deinterlace, write fits, etc).
The problem may be the os didn't allocate the amount of memory requested by the application. Try setting the \"SystemPages\" registry key to the value 0xFFFFFFFF. This has worked on Vista and x64 systems.
Another helpful option is to install the driver immediately following a fresh system boot.
Windows : On application startup you get the following error: "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem".
The C runtime libraries for the OS are probably out of date. The correct files can be downloaded here.
Linux : Single PCI board installed, but astropci_load creates two driver instances. Can cause Owl timeouts and incorrect images.
Make sure astropci_load only creates a single driver instance. Make appropriate changes to astropci_unload as well.
Linux : "Device or resource busy" on startup.
Close/exit any DS9 that may be executing.
Linux : "Cannot restore segment prot after reloc: Permission denied".
This is a permission issue with the SELinux Security Manager. Use the following commands on all necessary libraries to fix:
chcon -t textrel_shlib_t ''
semanage fcontext -a -t textrel_shlib_t ''
chcon -t textrel_shlib_t '
semanage fcontext -a -t textrel_shlib_t '
