Comment 25 Mohit Agrawal 2019-11-25 10:25:33 UTC
In 3.5 latest we fixed an issue specific to health check thread failure.
We fixed the issue from the bugzilla
https://bugzilla.redhat.com/show_bug.cgi?id=1752713

Can we try to reproduce the same on the latest RHGS-3.5 release?

Thanks,
Mohit Agrawal

I am closing the bug. 
Please reopen if you face the issue on the latest 3.5 release.
