named.service ramdom crashing

[larryg]

I'm running a caching name server on my system and it works fine for the most part but every few days it is crashing. The service dies with the following errors shown in the message log

Jun 7 03:48:05 LinuxServer systemd[1]: Reloading Berkeley Internet Name Domain (DNS).
Jun 7 03:48:05 LinuxServer systemd[5043]: named.service: Failed to set up mount namespacing: No such file or directory

And the message is current, there is no directory /bin/sh but it looks like named is trying to create it. I'm guessing its a permission error even though I have SELinux disabled.

Any thoughts on a workaround for this or is this a bug that needs to be reported as such.
