If that happens again, take a look at pg_stat_activity or ps output to
see what's going on. Something must be using the connections, a locked
table alone won't give you that error message.

Yeah, a vacuum is normally enough to keep the indexes in good shape. I'd
  suggest removing the REINDEX call and either letting autovacuum handle
it, or adding an explicit VACUUM call after the commit.
