So httpd survived Tuesday without crashing but crashed again yesterday and today.
In /var/log/messages I can see:
Nov 14 03:26:57 novak systemd[1]: Reloading The Apache HTTP Server.
Nov 14 03:26:57 novak systemd[739346]: httpd.service: Failed to set up mount namespacing:
No such file or directory

/usr/sbin/httpd: No such file or directory
Nov 14 03:26:57 novak systemd[1]: httpd.service: Control process exited, code=exited

And then a little later
Nov 14 03:26:58 novak systemd[1]: httpd.service: Killing process 230630 (nss_pcache) with
signal SIGKILL.
Nov 14 03:26:58 novak systemd[1]: httpd.service: Failed with result 'exit-code'.

subj=system_u:system_r:init_t:s0 msg='unit=httpd comm="systemd"
exe="/usr/lib/systemd/systemd" hostname=? addr=? terminal=? res=failed'
Nov 14 03:26:58 novak logrotate[739362]: ALERT exited abnormally with [1]
Googling the NAMESPACE error I find a post about /tmp or /var/tmp being symbolic links.
Neither are.
Yesterday I reinstalled httpd from scratch, last night it crashed again in the same way.
Does anyone know what user logrotate runs as? I’ve tried /bin/systemctl reload
httpd.service as root and it reloads as expected and am wondering if there’s something
else weird going on here?

Scott

Thanks for this.
Certwatch is uninstalled now, it just tells me if any of my certs have expired and as I
don’t have any on that box any more it’s kinda pointless :)
I’ve removed the stuff to hide the output from the apache restart in logrotate so I’m
going to let it run tonight and see if anything exciting gets logged
