Hello, I setup an Ubuntu 16.04 container on a host running Ubuntu 16.04 using the snap version of LXD 3.0.4. Everything was working great, so I upgraded the host to Ubuntu 19.10, and now I’m getting this error from my application in the container:
2019-12-11_18:59:26:02383 00:00:00:000 WARNING - PThread::_start: SCHED_FIFO - Failed to set scheduling parameters for PThreadPool
I suspect this is related to the
SYS_NICE permission, but I’m not sure. I tried granting SYS_NICE via the
raw.lxc setting, but that just took away other needed capabilities and it didn’t work well.
I read somewhere that the latest LXD grants all capabilities to unprivileged containers, so I tried upgrading to 3.18, but that didn’t help either.
Any advice would be appreciated.
