Description Sarah Bennert 2021-09-14 23:44:58 UTC
+++ This bug was initially created as a clone of Bug #2004295 +++

Tracking for 2.6.z

Description of problem:
  Opened as a follow-up to https://bugzilla.redhat.com/show_bug.cgi?id=1996660
  Observed an additional slower goroutine leak.

How reproduceible:
  Very reproduceible, must be run for an extended time to observe increase.

Steps to Reproduce:
  Allow for any stabilization between each step.
  While observing goroutines metric on virt-handler,
    1. Create and Start a batch of 100-300 VMs
    2. Delete all VMs in batch
    3. Repeat

Expected Results:
  Goroutines do not increase between VM deployments after initial deployment

Actual Results:
  Over the course of approximately 48 hours, goroutine count increased between 14-28 per virt-handler.
