cannot write PID to var/run/news
Completely new to Linux. My server mailbox is full of messages that say "cannot write PID to /var/run/news/shlock4495(example), no space left on device. I'm not sure what this means or if it's a problem, but it occurs hourly and is taking up too much space in my mailbox. I also get another one that says "Original message received from localhost, with all message information, the following address has fatal errors, news".
I could use some advice.
