Symptom
- Receiving DBSQL_SQL_ERROR dump.
- Database error text: "SQL message: [ASE Error SQL30294:HY000][SAP][ASE ODBC Driver] There is no server listening at HOSTNAME:PORT#."
- The work processes keep dying, it is necessary to restart SAP to logon
-
ASE bootup log shows that the server is listening on multiple listeners where IPV4 is static but IPV6 is dynamic (keeps changing) at each reboot:
server will listen on all networks present on host
network name HOSTNAME, interface IPv4, address 99.99.99.95, type nlwnsck, port 4901, filter NONE
network name HOSTNAME, interface IPv6, address 2222:0:ipv6:9e76:1cf3:fa73:ipv6.ipv6, type nlwnsck, port 4901, filter NONE <===server will listen on all networks present on host
