Hhm - I've had 1 script running, which start an UML - and another script, which every 3 minutes ssh into the started UML and run "halt; exit". Before that I manually did both steps. I let run the script solution for a while and did different things - but of course I cannot swear that I did not by accident recalled a command from a bash history command which killed processes (which I do have regularly to do if I test the UML with trinity). So likely my fault here - yes. -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
