I'm facing a strange problem and checked already a lot but maybe u will give me some good addittional thoughts.
We have a server in an openstack enviroment virtually running quiet fine. After a while, today it was after 72h, sometimes after eben less (24h e.g.). The External SAP ist not able to connect to that Servers DB to pull the data.
When I ping the SAP from that DB Server, SAP is again able to pull immediately..
I have a small business switch SG550xg between Openstack and network. The problem I'm not able to check the customer network means router and SAP cloud connection.
Before where the DB was baremetal installed, it was working quiet fine, but also there we hade the application server and DB server on the same system. Now it is separatet...
I expect ARP issues, but don't really imagine why..
I guess it can't be a routing issue..
maybe a state issue on the customer firewall, but why is ping triggering the state for another protocol.
with the ping I was able to have a stable situation for days..
