Dispatcher ping: "binding to source address X.X.X.X:XXXX failed: Address already in use" for TCP and TLS destinations

We have recently upgraded from 5.6.4 to 5.7.4.
No change in the KAMAILIO configuration.
On all upgraded servers we are now getting this message in the logs for
every destination when the dispatcher sends out OPTIONS to destinations
listed in the dispatcher list:
WARNING: <core> [core/tcp_main.c:1301]: find_listening_sock_info():
binding to source address X.X.X.X:YYYY failed: Address already in use [98]
The X.X.X.X being the servers IP address and YYYY being the servers
listening port for tcp and/or tls.
It's not consistent. For some servers it's every time OPTIONS is sent.
For others it's just now and then. udp destinations have no issues.
There are no other processes occupying these ports. Changing the
listening port on the KAMAILIO also results in the new port reported as
in use.
Dispatcher OPTIONS still seems to work for both tcp and tls.
Unsurprisingly using a dynamic, unprivileged port > 1023 and not the
server port as the source port, as it shouldn't. The packages are sendt
and a reply is registered. Inbound OPTIONS are processed as expected by
KAMAILIO on the listening port.
Have I missed something transitioning from 5.6 -> 5.7, or is this a bug?
Relevant config:
modparam("dispatcher", "ds_ping_method", "OPTIONS")
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "ds_probing_threshold", 2)
modparam("dispatcher", "ds_ping_interval", 120)
modparam("dispatcher", "ds_ping_from",
"sip:ping@xxxxxx.xxx")
modparam("dispatcher", "ds_ping_latency_stats", 1)

Hello,
we also observed this going from an older release to 5.7.x this week. It seems to be
harmless, but its generating indeed a lot of warnings.
Cheers,
Henning

Hello,
+1
Kamailio 5.7.3 logs warnings on every call to *t_relay()*, not just
dispatcher OPTIONS.
When *tcp_reuse_port=yes* there are no warnings, but in this case the
client sends requests from the server port.
Is there another W/A?
