Hi,
I'm looking for the simplest workaround for a bug in the reload implementation
of upstart as shipped with Ubuntu raring. It manifests itself by loosing track
of the exec process. If it does not ring a bell, the steps to reproduce from
a fresh Ubuntu raring installation are here :
could disclose her/his identity
to RedHat or any other trusted third party. Do you see any reason why RedHat

Hi Kevin,
The following patch is initializing the array in a lock protected / not thread
sensitive part of code.
https://github.com/ceph/ceph/pull/1621/files
Unless I'm mistaken, it ensures that it never happens automagically. The first
few tests that were run indicate it's not more broken
?
There is no easy way to use the logs / events to significantly reduce the
randomness of the workload ? I honestly have no clue ;-)

IIRC you figured out how to use

Would it be possible to display the content of the log files if an error
happens ?

performs :-)
