Hi All, We're now seeing the following message: ERROR remoteListenThread_1: timeout for event selection At the same time as: sched_mainloop: select(): Bad file descriptor appears on standard error. This appears to be a very similar problem to a post last year: http://gborg.postgresql.org/pipermail/slony1-general/2004-October/000747.html In a reply, Jan suggested that this locking problem would be fixed in 1.0.3. We're running 1.1.0. Can an anybody comment as to whether this really has been fixed? Or should we be looking at the patch suggested?
