Hi Massimo,

        I can see that there are 79 lhcb jobs running at Legnaro. Out of
them, 18 are actually "Running" the Monte Carlo Generation and the rest
are "Waiting for Data Transfer", most of them since early yesterday
morning.

        All data transfer operations are supposed to be wrapped with
timeout to avoid these locks. I can not guarantee that there are no
errors in the logic. Can you please check a couple of this stuck jobs to
see what is currently being execute?

        Doing a "netstat" could bring some more info about possible
reasons for the hangs.

        Some affected WN are:
cmsfarm-01-14.lnl.infn.it
cmsfarmbl01.lnl.infn.it
cmsfarm-01-03.lnl.infn.it

        If you can please do these checks and let me know the result, it
can help us to avoid the problem in the future.

        If you see gridftp stuck processes please kill them, the
wrappers will retry.

        Regards

                Ricardo

PS: jobs will eventually be killed by proxy expiration, but this only
happened in about 2 day from now.
