I have cron jobs and every now and then they fail. Just after log message that the command has started, there is
grandchild #X failed with exit status 3 message.
On the next run scripts finishes correctly. It happens to different scripts with different run periods (from minutely to once-a-day scripts). There seems to be no pattern.
I ran scripts in crontab in
strace. The problem is the script gets killed because of
--- SIGBUS (Bus error) @ 0 (0) --- exit_group(3) = ?
However, still don't know why this is happening.
