Hi all,
I'm experiencing a bad behaviour of anaRecoil vs the newly produced
rootfiles.
When I try to run over those rootfiles (placed in AWG7 and AWG8) I ran
into misterious (maybe only for me :)) ..) crashes that are randomly
placed (and randomly disappear) along the chain that I'm processing.

An example:
I've tried to ran over generic MC:
job a: 2000 rootfile chain
job b: 2001 rottfile chain
job c: the sum of the proceeding two
this resulted in
a) run without crash
b) and c) crashed.

Those jobs were ran in parallel.

The same I got for cocktail
(in this case the crash is only for job b) ).
On data, today, I do not have any crash
(but yesterday, runnning on the same files, job a and c were crashed).

All the jobs were ran in parallel.

This means that we can't run job in parallel?
Or maybe there's something wrong in the way that our root jobs are
accessing data?

btw, the output of QA script will appear (if all works well) in
http://www.slac.stanford.edu/~asarti/recoil/production/QA_081602.html

thanks for the help,
Alessio
