[defect]: server hangs after TLS reinitialise to Radsec home server

[olddanmer]

What type of defect/bug is this?

Crash or memory corruption (segv, abort, etc...)

How can the issue be reproduced?

Freeradius 3.2.3, the complete configuration you can see at debug below. I setup freeradius 172.29.5.19 (int IP 10.250.0.2) as proxy, with Radsec as the first of home servers. This part of configuration is below

 home_server securew2-radsec-global {
         type = auth
         ipaddr = 44.238.1.2
         port = 2083
         proto = tcp
         response_window = 4
         response_timeouts = 2
         zombie_period = 3
         revive_interval = 3600
         tls {
             private_key_file = ${certdir}/ssl/radius-proxy.myo.com.pany-radsec.key
             certificate_file = ${certdir}/ssl/radius-proxy.myo.com.pany-radsec.crt
             ca_file = ${cadir}/ssl/securew2_radsec_ca.pem
             fragment_size = 8192
             cipher_server_preference = yes
             tls_min_version = "1.3"
             tls_max_version = "1.3"
          }
 }

At the start, freeradius proxy initiates TLS connection to port 2083 of remote Radsec Radius server. Sometimes remote Radsec Radius stops the session by sending TCP FIN and RST packets and at that time I see in the logs

Info: ... shutting down socket proxy (10.250.0.2, 53879) -> home_server (44.238.1.2, 2083) (1 of 16)
Info: ... adding new socket proxy (10.250.0.2, 38163) -> home_server (44.238.1.2, 2083) (1 of 16)

After that, freeradius usually reinitiates TLS session to remote Radsec Radius and continues to work fine. But sometimes something happens during TLS initialization and freeradius completely hangs. When freeradius hangs I don't see anything in the logs. If I start tcpdump at that time, I see only access-requests from clients, but freeradius answers nothing. I must restart freeradius to repair it. The issue happens a couple per day and it's hard to catch it.

I attached below debug with -X, I stopped freeradius about two minutes after it had hanged. During those two minutes, there was a couple of dozens of access-requests, but freeradius didn't answer at all. Here is also wireshark screenshot of that moment

Also, I have to add, that when freeradius works fine I see

(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) recv TLS 1.3 Handshake, NewSessionTicket
(0) (TLS) Handshake state - Client SSLv3/TLS read server session ticket
(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) recv TLS 1.3 Handshake, NewSessionTicket
(0) (TLS) Handshake state - Client SSLv3/TLS read server session ticket
(0) (TLS) recv TLS 1.3 Handshake, NewSessionTicket
(0) Marking home server 44.238.1.2 port 2083 alive

But before it hangs, I see almost the same logs, but without the last string

(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) recv TLS 1.3 Handshake, NewSessionTicket
(0) (TLS) Handshake state - Client SSLv3/TLS read server session ticket

(0) (TLS) Handshake state - Client SSL negotiation finished successfully
(0) (TLS) recv TLS 1.3 Handshake, NewSessionTicket
(0) (TLS) Handshake state - Client SSLv3/TLS read server session ticket

Described hang seems like a bug, please take a look. Thanks in advance!
