My caffeing level is too low yet to know for sure, but I think this is
innocuous (particularly so if there's a single file in that directory,
because then there's nothing to truncate anyway).

[GENERAL] Got could not truncate directory pg_multixact/offsets: apparent wraparound

2009-09-03 Thread Gordon Shannon

Hello,  running 8.4 on Centos.  Been running production for 6 months.  Never
saw this message until tonight:

  LOG: could not truncate directory pg_multixact/offsets: apparent
wraparound

In case it helps...

Output of pg_controldata:
Latest checkpoint's NextMultiXactId:  145725622
Latest checkpoint's NextMultiOffset:  394849408

Contents of pg_multixact/offsets:  08B0
Contents of pg_multixact/members: 178B

In conf file:
vacuum_freeze_min_age = 10  # (1 billion)
autovacuum_freeze_max_age = 15  # (1.5 billion)

Oldest txn in cluster (pg_database.datfrozenxid) : 648

Should I be concerned? 

Thanks
Gordon
