(Very) Occasionally, we see these errors from Slony:

ERROR  remoteListenThread_1: "listen "_schema_name"; " - ERROR:  could not read block 2 of relation

To the tune of, seen it about 5 times in the last 6 months.  Now that we
have a few examples of it, it seems to occur only when the server is
under heavy load.

Is there anything here to be concerned about?  Or is this just a byproduct
of the database responding slowly at times?

This is PostgreSQL 8.3 on FreeBSD 6, using the latest Slony 1.2  (although
there have been varying versions over the last 6 months)
