[jira] [Comment Edited] (HDDS-3254) Memory leak of datanode
[ https://issues.apache.org/jira/browse/HDDS-3254?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17065422#comment-17065422 ]

------------------------------------------------------------
[~shashikant]I deploy 550 datanodes and 30 s3gateways on k8s. Python client starts 600 threads to send write, read, delete request to 30 s3gateways. Python client run 4 days, and then some datanodes physical memory increase in a short time as the image shows, but the other datanodes physical memory is very small. I'm not sure whether this problem show up only with multiraft enabled. I will continue to find it. Maybe it's not memory leak.
