Hi Pierangelo;

What bothers me is that the regular client requests to the consumer receive
(scarcely and randomly) "Time Limit Exceeded" at checkpoint time.

The replication requests to the master also receive this error after 3600
seconds when I'm synchronizing a new empty replica (as though I set timelimit
unlimited for the sync client), but this is not a problem for me because the
syncrepl client makes a new connection to the master and everything works well.

Best regards
Ali
