Local Health Check Warning reasons

Hello,
after update to .Net 5 my Orleans project started to have warnings about GC timer is not triggered at time. It happens regularly, for already quite some time, and i am not sure where to look for a reason of this.
Logs:
`Orleans.Runtime.MembershipService.LocalSiloHealthMonitor - Health check participant Orleans.Runtime.Catalog is reporting that it is unhealthy with complaint: Catalog.GCTimer timer should have fired at 3/26/2021 6:27:55 AM, which is 00:00:07.2431620 ago`
`Orleans.Runtime.MembershipService.LocalSiloHealthMonitor - Self-monitoring determined that local health is degraded. Degradation score is 1/8 (lower is better). Complaints: Health check participant Orleans.Runtime.Catalog is reporting that it is unhealthy with complaint: Catalog.GCTimer timer should have fired at 3/26/2021 6:27:55 AM, which is 00:00:07.2431620 ago`

After some time logs disappear with maximum delay of 15 seconds, but then after some time (minutes to hour) its come back.

I would really appreciate if someone can advise on how to tackle this issue. I guess its not very serious since no issues with application's operation, but it surely doesn't look like indented.
