I've noticed jobs in /etc/cron.d/ not running, the odd thing is that X amount will run but then the rest won't.
I've read comments from people about not using a '.' in the filenames, none of my files have any dots in them.
I've also read that you should always place a blank line at the end of each file, but that didn't seem to make any difference.
In the end I stripped out ALL comments from every single file in /etc/cron.d/, this made all jobs run correctly.
Cron was not putting any errors messages in to /var/log/syslog or /var/log/messages, there is no /var/log/cron(d).log
Has anyone encountered anything like this before? If so is there a solution for commenting without it causing problems?
