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 = 1000000000 # (1 billion)
autovacuum_freeze_max_age = 1500000000 # (1.5 billion)

Oldest txn in cluster (pg_database.datfrozenxid) : 648

Should I be concerned?

Thanks
Gordon
