Opsview hangs after some time

Open megabreit opened this issue 5 years ago • 2 comments

Opsview hangs after some unknown (longer) time displaying only the top menu (color and sort options) and no cluster anymore.

netstat in the kubeopsview container shows >2500 establisched connections to the redis pod: netstat|grep kube-ops-view-6b6b5b6964-mhccj|wc -l 2554

[..] tcp 2458306 0 kube-ops-view-6b6b5b6964-mhccj:57588 kube-ops-view-redis.ocp-ops-view.svc.cluster.local:6379 ESTABLISHED tcp 1658433 0 kube-ops-view-6b6b5b6964-mhccj:52628 kube-ops-view-redis.ocp-ops-view.svc.cluster.local:6379 ESTABLISHED Active UNIX domain sockets (w/o servers) Proto RefCnt Flags Type State I-Node Path

Runtime is Openshit 3.11 (Kubernetes 1.11) with increased redis memory limits compared to the original deployment.

Looking through the other open issues, this is probably similar (or duplicate) to #240

Some more debugging: ops-view is starting with 3 established connections to redis. Every time the browser window is reloaded (either by reload button or the reload option) a new established connection appears. It seems that connections never terminate and consume resources until it crashes/hangs.
