Hi Chad/GoCD Team,

Docker VersionDockerVersion: 20.10.25
ECS Agent Version1.84.0
issues

1) ECS Ec2 servers, we have given 12 as max in the cluster profile

But it's shown max 10 servers in the error logs



2026-02-19 02:05:41,739 INFO  [899991@MessageListener for ServerPingListener] ECSElasticPlugin:72 - [server-ping] Cluster has total 12 LINUX instances which is beyond permissible limit(10). Terminating idle instances.
 

is there any way to limit extend?

due to this max as 12 , ui showed 11 , keep on one ec2 server, span up and terminating.....

Is there any way to limit the extension? 
Due to a maximum of 12, the UI shows like (10),(11),(12)...etc. We need to keep  on one EC2 serverspinning up and terminating instances. 

During this time, jobs or pipelines are being assigned to terminated instances.
2) ec2 servers are not terminated as we expected in profile time intervals

StopLinuxInstanceAfter
60
TerminateStoppedLinuxInstanceAfter
2
manually terminating the ECS Ec2 servers


Production jobs were delayed last week by 40 minutes due to this terminated server registered for the task(out of 12 to 10 )


3)Regarding ECS EC2 tasks, is there a way to assign them equally across each EC2 server? 

For example, if there are 5 servers and 50 tasks, can we configure it so that each server runs 10 tasks?


Please find the attachment screenshots via a separate email

ECS Ec2 server is registered and healthy but container is not assigned



regarding above issues we have connected to AWS support team 
ECS
EC2
these 2 teams said ec2 and ec2 cluster is healthy , issue with plugins (go-agent)
