Re: WO Apps do not restart automatically after one server upgrade...

Hello,

Thank you for your information... Unfortunately, I did not had the =20
opportunity to perform this procedure...

While I was trying to "control" the server thru Timbuktu, the server =20
crashed and reboot automatically... I then launched a big "Norton =20
Disk Doctor" on the server system disk: it found really many =20
errors... I even had to make a "Recover Disk" on it...

After the server restarted, all the WO Apps were automatically =20
restarted !

After all this, I deployed fresh new versions of these WO Apps and =20
restarted the server: everything was restarted automatically, all the =20=

services and the WO Apps...

In my case, it seems that the problems were related to garbage in the =20=

system disk structures... May be you should check your xserve  system =20=

disk ?

Nevertheless, I am a bit disappointed because the server system disk =20
is really fresh: it has been formatted and prepared just 3 month =20
ago... What can create such a garbage when the server never crashed =20
(only once) ?

Regards / Cordialement ;-),
