    The SE sometimes (1 per 8 intoi my server) can't restore the subscriptions. It seems that's a thread unsafe issue. The trace:

    [Petals.Container.Components.petals-se-kpi]-WARNING 2011-01-12 11:08:02,996 unable to restore the subscription references
[Fatal Error] SubsReference.xml:1:1: Premature end of file.

    We can see that the Exception isn't cught by the petals logger too (we see [Fatal Error]).
    If we restart, we have again the trace. It seems that we continue to receive the notifications (so is it ok or completly lost and recreated from scratch?)

With some tunning, I get the previous error. It occurs at least one restart per five.
