gmond/ganglia not starting with systemd #323

Closed adambarnett52 closed 1 year ago

adambarnett52 commented 3 years ago

Hi,

Running ganglia/gmond, running under systemd the gmond service does not start and casue systemd to hang waiting for it to start, it does not timeout.

My systemd service file looks like this, which already has the fix in for network-online.target

# /usr/lib/systemd/system/gmond.service
[Unit]
Description=Ganglia Monitoring Daemon
After=multi-user.target
After=network.target

[Service]
Type=forking
ExecStart=/usr/sbin/gmond 

[Install]
WantedBy=multi-user.target

# /etc/systemd/system/gmond.service.d/override.conf
[Unit]
After=network-online.target

Running a trace shows the following 

c3158b3 /root # strace -ff -p 103835
