Apparently it means that OpenVZ doesn't work too well :-( --- it hasn't migrated the contents of shared memory accurately. This could be a synchronization type of problem, eg contents of process local memory and shared memory not copied at the same instant. IIRC one of the main reasons for "hash table corrupted" panics is failing to find a hash table entry that is expected to be there according to some other state information. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
