All the sudden today I started getting a weird problem when trying to edit files in Eclipse. I could save the file once, but on a subsequent save I was getting the following error:
If I closed the file and re-opened the file, I could save it again but only once.
This had me really scratching my head. My projects actually exist on my LAN as I save the files directly to my personal Dev Server. I thought the problem might have related to some kind of network problem, so I went through a bunch of steps—including rebooting both my Dev Server and my Workstation—but nothing was working.
Finally I got the bright idea to disable ESET Smart Security (which is the new version of the NOD32 scanner.) What do you know, things started working again. I had to play around with things for a while before I was able to figure out what exactly was causing the problem.
It turns out the "Real-time file system protection" was causing the problem. I'm not sure why it's causing the problem, but the fix is easy enough.
NOTE:If you prefer, you could just add the specific extensions you're having problems with to the "Exclude" filter list, the option is up to you.
I'm going to open up a ticket with ESET's support and see what they have to say about this.
