Hi all
We are running postgres 9.1 on CentOS 5. We can’t start up postgres . It
complains about memory allocation . Please help
FATAL: shmat(id=3342337) failed: Cannot allocate memory
# - Memory -

# (change requires restart)

# (change requires restart)
# Note: Increasing max_prepared_transactions costs ~600 bytes of shared
memory
# per transaction slot, plus lock space (see max_locks_per_transaction).
# It is not advisable to set max_prepared_transactions nonzero unless you
# actively intend to use prepared transactions.
