Our developers recently updated to the latest version of vim and sense then when they edit files from the network share hosted on a FreeNAS server, they eventually cannot write the file, as the .swp file throws them a read only type of error.
I checked the permissions and they have full access. If I close VIM and delete the .swp file, they can then open the file and save the file again till the issue happens again.
Is this a FreeNAS side effect where it could be holding a file in memory?
