You should be able to narrow down which one is the culprit. unfortunately I cannot reproduce the panic this way. What I did was: # cd /etc/periodic/daily # for file in `ls` do echo $file ./$file done I run it twice, I could see all scripts executing one after another, but no panic. Perhaps something else is happening at the same time as daily scripts? But I cannot find what. Thanks Anton
