Public bug reported:
In fast machines one can see a race condition related to the old-style
sysinit scripts that upstart runs. I noticed this on a virtual machine.
The symptoms are:
- winbind is hung on a futex call (only one winbind proc is visible, unlike
the usual situation)
- xrdp is not launched because start-stop-daemon is also hanging on a futex call
- ...
Perhaps these daemons are being launched before networking or DNS.
Process 916 attached - interrupt to quit
futex(0xb666cd08, FUTEX_WAIT_PRIVATE, 2, NUL
However if we insert an S10sleep script on rc2.d, with
sleep 5
the problem disappears. That is, winbind and xrdp start up normally.
Notes:
I have the latest upstart package installed.
The problem is reproducible
