# Flow settings:
# By default, the reserved memory (memcap) for flows is 32MB. This is the limit

# more memory usage for flows.
# The hash_size determine the size of the hash used to identify flows inside
# the engine, and by default the value is 65536.
# At the startup, the engine can preallocate a number of flows, to get a better
# performance. The number of flows preallocated is 10000 by default.
# emergency_recovery is the percentage of flows that the engine need to
# prune before unsetting the emergency state. The emergency state is activated
# when the memcap limit is reached, allowing to create new flows, but
# prunning them with the emergency timeouts (they are defined below).
# If the memcap is reached, the engine will try to prune prune_flows
# with the default timeouts. If it doens't find a flow to prune, it will set
# the emergency bit and it will try again with more agressive timeouts.
# If that doesn't work, then it will try to kill the last time seen flows
# not in use.

# seconds that the engine will wait to free the flow if it spend that amount
# without receiving new packets or closing the connection. "closed" is the
# amount of time to wait after a flow is closed (usually zero).
#
# There's an emergency mode that will become active under attack circumstances,
# making the engine to check flow status faster. This configuration variables
