Reporting on 11.2 broken

[Jose Baars]

Definitely not related to USB sticks. I do not have USB sticks in my system, booting from SSD.
The message might indicate some kind of race condition in the collectd code.

Running 11.2-5. Everything has been great for a couple months. Then all reporting stopped on the dashboard. Didn’t have time to deal with for a couple weeks. Upon looking at the monitor attached to the server , which I rarely do, I noticed the same error message about failure of nanosleep- no child process as reported by others here. I found this thread and checked and collectd had indeed stopped. I restarted the collectd service and reporting is back!
This is a bug, does anyone know if it has been reported yet?

For what it’s worth, I am using a mirrored SSD pair for the boot pool and see no errors there.

I had the same issue. In my case, I remember once I changed the "system dataset" in the system tab. Because I have two redundant USB stick for Freenas and knowing that USB stick are prone to fail, I changed where the logs and system evens were stored.

To do that, I used a dataset on my pools. Then, later, I just forgot that and the reporting stopped working(probably when I configured the dataset differently). Bethween the moment of the fail and the time I changed the place to stored the logs, I just didn't remember the change I have made.

Then one time I just worked up I find out that it might be just that. So check if the system dataset is correctly configured, that might be just that.

My version of freenas is 11.2 U7
