installed the moodle with 3 mariadb node with galera wsrep replication cluster all are masters & haproxy and keepalived.
02 web servers with nginx ,mariadb client with haproxy, seperate memcache server and NFS.
All are working but in mdl_logstore_standard_log is continuously logs with userid '0' zero hence no user is logged via web.
if we stop the nginx in both the web server the logs with userid '0' stopped,
we start webserver logs continously inserted in mdl_logstore_standard_log table.
