397534 - fix hdiutil problems on talos slaves running in Buildbot

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[[e-mail] (:bhearsum)]

hdiutil often fails silently on os x talos slaves that run from Buildbot. It appears to only happen after a successful build. The only way to work around it is to restart the Buildbot slave.

There is nothing in the system logs on a failure. When hdiutil works properly this is in the log:
KernelEventAgent[32]: tid 00000000 received unknown event (12)

When running hdiutil with -verbose I got this:
2007-09-25 13:12:49.905 hdiutil[6851] error: unable to set up framework server.
DIHLDiskImageAttach() returned 6
hdiutil: attach failed - Device not configured

I found this page with google: http://lists.apple.com/archives/Darwin-dev/2004/Oct/msg00044.html

The poster believes that hdiutil fails when called from a daemon whose parent process has terminated. So, this leads me to believe that hdiutil will fail when the ssh session that I start Buildbot from is closed.

I've started the Buildbot slave from a terminal running in the VNC session. I'm going to let it run a few times, and if it works I'll see if closing that terminal window will mess it up.
