Describe the bug

I'm running argocd-image-update to update some images based on semver strategy. Everything works fine in the beginning, but after some time (couple days) I started getting error says "connect: cannot assign requested address" and nothing works. Restarting pod could bring it back to working state, but the issue will return in a couple of days.

It seems the connections are never closed.

$ netstat -anp  | grep ESTABLISHED | wc -l

Image-updater v0.12.0 (helm chart v0.8.0)
