Hello again,
I think I have resolved this issue by adding the following line to my
relevant service startup files:
RestartSec=60s
I presume the line forces a restart within 60 seconds (or with the time
allowance of 60 seconds). Actually according to this source:
http://www.dsm.fordham.edu/cgi-bin/man-cgi.pl?topic=systemd.service&sect=5
it is the former - the sleep time before attempting a restart.
I put the line directly below the "Restart=..." line. See
my dnscache.service for example:
[root@ns99 system]# more /usr/lib/systemd/system/dnscache.service
[Unit]
Description=An iterative DNS resolver daemon
Documentation=man:dnscache(8)
Requires=network.target
After=network.target
[Service]
Restart=always
RestartSec=60s
PIDFile=/var/run/dnscache.pid
ExecStart=/usr/sbin/dnscache
[Install]
WantedBy=multi-user.target
[root@ns99 system]#
Cheers,
Boris.
