From ARIS 10 SR4, the elastic runnable (elastic search) requires more virtual memory on your Linux operating system in order to prevent indices from causing out-of-memory exceptions. On the machine where the elastic runnable is installed, check which value the vm.max_map_count system parameter is currently set to.
For this, use the sysctl vm.max_map_count command. If the value is lower than 262144, change it to 262144.
To change the value for this session only, use the following command (root access permissions required):
sudo sysctl -w vm.max_map_count=262144
This command changes the value for the current session only. After a reboot, this change is undone.
To change the value persistently, add this line to the sysctl.conf configuration file that is available in the ARIS installation directory on your machine:
vm.max_map_count=262144
