Hello, We installed Datastax community edition, on 8 nodes, RHEL7. We inserted some 7 billion rows into a pretty simple table. the inserts seem to have completed without issues. but ever since, we find that the nodes reliably run out of RAM after few hours, without any user activity at all. No reads nor write are sent at all. What should we look for to try and identify root cause?
[root@avesterra-prod-1 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.2 (Maipo) [root@avesterra-prod-1 ~]# rpm -qa| grep datastax datastax-ddc-3.2.1-1.noarch datastax-ddc-tools-3.2.1-1.noarch [root@avesterra-prod-1 ~]# The nodes had 8 GB RAM, which we doubled twice and now are trying with 40GB... they still manage to consume it all and cause oom_killer to kick in. Pretty much all the settings are the default ones the installation created. Thanks, Mohamed.
