I have a proxmox server with a ubuntu lxc container. cron is not working. I am working this as root:
cron -l
cron: can't lock /var/run/crond.pid, otherpid may be 21952: Resource temporarily unavailable
ls -l /var/run/crond.pid
-rw-r--r-- 1 root root 6 Jul 27 13:45 /var/run/crond.pid
ps -ef | grep cron
root 21952 1 0 13:44 ? 00:00:00 /usr/sbin/cron -f
kill 21952
rm /var/run/crond.pid
apt-get install --reinstall cron
service cron restart
cron -l
cron: can't lock /var/run/crond.pid, otherpid may be 21982: Resource temporarily unavailable
ls -l /var/run/crond.pid
-rw-r--r-- 1 root root 6 Jul 27 13:45 /var/run/crond.pid
