Hi. We have updated our staging server from 5.0.5 to 5.0.6, and have started to experience strange behavior.
After a while, server rejects all new connections from .NET client. All write or read attempts end up in ConnectionClosed exception.
Restarting the apps does not help.
Normal operation resumes only after we restart server instance.
We are running on bare metal, WIN 2016 server, 250GBSSD, 64GB RAM.
Any pointers as to what can saturate and block server in this way? Our code has not changed, and it worked until last update.
