Thank you very much for the reply. We typically see no visible replication delay over 5 minutes ever. Today we saw a delay of over 3 hours, and no obvious increase in workload either on the provider or the subscriber. I also did not see the LSN advancing whatsoever in terms of applying changes. I first checked for long-running transactions on the master but there was nothing too unusual except an ANALYZE which I promptly killed, but with no improvement to the situation. I found the messages above using strace after canceling the subscription and finding that the process was taking extremely long to cancel. There are 2.1 million files in pg_replslot which I don't think is normal? Any ideas as to where I should be looking or what could cause this? Thanks, Jeremy
