Being the only "*nix" person in our office, I've been designated to fix a problem on a old SCO server.
I know what you're thinking because I thought the same thing; "it's a dream come true!" but I didn't let my enthusiasm show.
The problem is that cron was "hanging" in the middle of the night roughly every second day. The log show that it was throwing an error: "Cannot create temporary file" around 4:30am every second day, but the exact time and process running isn't always the same.
/tmp and /usr/tmp are normal looking and there should be enough free disk space so that isn't the problem.
Thinking that maybe something was suddenly chewing up disk and then being cleared I setup a little cron to log disk usage every 15 minutes.
Now cron hangs _every day_ at about 16:30!
In order to restart cron, its FIFO pipe file has to be deleted and the box rebooted.
Again, disk usage is not a problem.
Anyone know anything about how SCO cron works?
