System.IO.IOException every 5 seconds

The tentacle is working, but the logs are filling with the following error message every 5 seconds. Do you have any suggestions on how to fix this? It’s a listening tentacle, version Calamari folder says version 3.1.2. Server version 3.2.0

Hi Lars,

Thanks for getting in touch. There’s no way currently to suppress these messages from the logs, but the logs are rolling so they will eventually get deleted. Can you confirm that the machine at the IP address mentioned in the log is the Octopus server, and not some other server that is connecting to the Tentacle (not, say, a legacy 2.6 Octopus server or some kind of network scanning software)?

Are there any firewalls between the Octopus and Tentacle? Sometimes these will shut down connections prematurely.
