I received this error twice over the last 3 weeks, just scrolls this message. I can not break to get back to a shell, end up having to reset. Think I have space but not sure what is up:

32GB ECC RAM
1 Pool/ 2 dev: 5x 4TB drives Z3, 5x 3TB drives Z3
Pool: Available Space: 5.39TiB (54% used)

Typically this is a sign of memory stress. You haven't explained what you're using the filer for, or if you might be running anything like jails or VM's that might cause unusual memory stress.

I would advise against running an RC version of FreeNAS if you're experiencing problems. Often, memory leaks and other issues are found during the release candidate cycles and this may be a resolved issue.

Beyond that, there's nothing here screaming out as to a problem, but there also isn't a lot of information to go on. If this happens more often, you might want to consider setting up an hourly cron job to snap "top(1)" activity snapshots into your pool so that you might get an idea if there's something mongo running eating your RAM.

Using iocages; plex, emby, sonarr, radarr, lidarr and sabnzbd. No VMs. I never had this issues using 11.2 so I am thinking it might be something with 11.3.

Thanks

I have similar plugins running on my system. It appears it was lidarr which has a memory leak and would start chewing swapspace after about a week. I disabled this plugin and my system has been working fine for 2 solid weeks with no sign of swapspace usage.

So that's a good thing to check.
