Issue - Linux memory limits

FeatureBase Community may exceed memory limits whilst:

importing and ingesting data
running queries

Possible cause

Memory settings may be configured incorrectly:

in featurebase.conf
for the current session
for persistent sessions

Solutions

Alter the FeatureBase max-map-count

Alter max-map-count parameter

Alter memory limits for current session

ulimit affects only the current shell and its child processes. You may need to launch a new shell as root to raise the ulimit to an appropriate value.

Open a CLI then run the following command with an appropriate value:

ulimit -m <value>

Verify the change:

ulimit -m

Increase memory-mapped regions for the current session
