Yesterday, I had twelve thousand "cache lookup failed for type N"
messages, like this:
2010-09-20 00:00:00 PDT ERROR: cache lookup failed for type 14237017
2010-09-20 00:00:00 PDT CONTEXT: SQL statement "INSERT INTO
mycluster.sl_log_2 (log_origin, log_xid, log_tableid, log_actionseq,
log_cmdtype, log_cmddata) VALUES (1, $1, $2,
nextval('mycluster.sl_action_seq'), $3, $4);"
The context is always Slony sl_log_2 table. All twelve thousand
errors occurred within 40 minutes. This did happen right after a
Slony cluster set drop and recreate.
What does "type 14237017" mean? What cache are we talking about?
I am concerned because of PostgreSQL classification of ERROR rather
than WARNING. What does this mean? I want to understand what
happened if there is anything I can do about it.
PostgreSQL 8.4.4
Slony1 1.2.20
Thanks,
Aleksey
