Stuck at "Starting master: OK"

Dear all,

I am trying to start a PROOF session using some workers from PROOF-Cluster (as I have done many times),
but for some reason I got stuck at “Starting master: OK”:

root [0] p = TProof::Open(“arodrig@proof.ifca.es:1093”)
Starting master: opening connection …
Starting master: OK

Setting a log level the only message I get is:

110623 13:30:58 001 Proofx-E: Conn::SendRecv: reading msg from connmgr (server [proof.ifca.es:1093])
110623 13:33:29 001 Proofx-E: Conn::SendRecv: reading msg from connmgr (server [proof.ifca.es:1093])
[…]

And I could not find any hint on how to deal with this error. Do you have any idea?

I do not have any other errors in the log master, neither in the logs for the workers.

Thanks,
Ana.
