How do I avoid TCP/IP port conflicts on a RHEL system running an SAP application?
Issue
- Another process chose an ephemeral port that conflicts with SAP HANA System Replication (HSR).
- Corosync is listening on port
40003/udp, which prevented replication in a multi-tenant SAP HANA cluster.
Environment
- Red Hat Enterprise Linux 6, 7, or 8 (with the High Availability Add-on)
- SAP HANA
