389ds memory limits in kubernetes

    Hello,
    I have a StafulSet in Kubernetes based on
https://directory.fedoraproject.org/docs/389ds/howto/howto-deploy-389ds-on-openshift.html
    I set a memory limit to 6Gi
              image: quay.io/389ds/dirsrv:latest
          ...
            limits:
              memory: "6Gi"
    Doing some performance test with 4k entries (query every entry in
      a loop), the used memory is increased on every test until
      kubernetes kills the pod (twentieth test aproximately).
    terminated

      Reason:Reason: OOMKilled - exit code: 0
    Logs only shows 

      
    NOTICE - ldbm_back_search - Unindexed search: search base="ou=myou,dc=XXX,dc=XXX" scope=2 filter="(objectClass=nsperson)" conn=18 op=46
    when
      I get all entries in my ou

    
    ldapsearch -D "cn=directory manager" -W -b "ou=myou,dc=XXX,dc=XXX" -H ldap://localhost:3389 -s sub "(objectclass=nsPerson)" uid
    Maybe a tunning problem or a mem leak? 

    
    Regards
