Elasticsearch not running after upgrade to 7.0.8 (from 6.2.4)

[1]: initial heap size [536870912] not equal to maximum heap size [1073741824]; this can cause resize pauses and prevents mlockall from locking the entire heap

by setting

-Xms1g
-Xmx1g

seafile-server-latest/pro/elasticsearch/config/jvm.options

original setting was:

-Xms512m
-Xmx1g
