If the network high availability (HA) daemon sod is configured to use a port number that is lower than 1024, the binding fails with a permission-denied error. This affects binding to ports on both management and self IP addresses. Example log messages: /var/log/ltm err sod[2922]: 010c003b:3: bind fails on recv_sock_fd addr 1.2.3.4 port 1023 error Permission denied. notice sod[2992]: 010c0078:5: Not listening for unicast failover packets on address 1.2.3.4 port 1023. /var/log/auditd/audit.log type=AVC msg=audit(1578067041.047:17108): avc: denied { net_bind_service } for pid=2922 comm="sod" capability=10 scontext=system_u:system_r:f5sod_t:s0 tcontext=system_u:system_r:f5sod_t:s0 tclass=capability
