[jbosstools-issues] [JBoss JIRA] (JBIDE-26697) Possible memory leak during Loading projects job when using CRC

[Jeff MAURY (Jira)]

    [ https://issues.jboss.org/browse/JBIDE-26697?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13790092#comment-13790092 ] 

Jeff MAURY commented on JBIDE-26697:
------------------------------------

No this one is probably on the IDE site and not limited to CRC.
It has been discovered with CRC because CRC wrongly exposes kubeadmin as the user to use so as you're admin on the cluster, there are a lot of projects that are accessible (OCP4 added probably lots of projects).
And for each project, we install several listeners (one per resource type) and each listener is creating a thread through okhttp
Maybe we should switch to Kubernetes events but I'm feeling it is less verbose (needs to be checked)
I think it an be reproduced on OCP3 with a cluster with lots of projects
