Hi @jens-skribble, thanks for reporting the bug.
I was able to reproduce the bug in both scenarios:
1. Using provided reproduce.sh script.
2. MRE from local APISIX (traditional mode)
a. Configure `config.yaml`
```
apisix:
tracing: true
ssl:
enable: true
listen:
- port: 9443
deployment:
role: traditional
role_traditional:
config_provider: etcd
admin:
admin_key:
- name: admin
key: <redacted>
role: admin
```
b. Run `make run`
c. Configure SSL cert and key (can generate thru openssl, i just copied
the one provided in reproduce.zip)
```
curl http://127.0.0.1:9180/apisix/admin/ssls/1 -H 'X-API-KEY: <redacted>' \
-X PUT -d "{
\"snis\": [\"localhost\"],
\"cert\": \"$(cat /path/to/server.crt)\",
\"key\": \"$(cat /path/to/server.key)\"
}"
```
d. Create route
```
curl http://127.0.0.1:9180/apisix/admin/routes/1 \
-H 'X-API-KEY: <redacted>' \
-X PUT -d '{
"uri": "/*",
"upstream": {
"type": "roundrobin",
"nodes": {"httpbin.org:80": 1}
}
}'
```
e. Trigger the crash (two requests on same TLS connection):
```
curl -sk \
-o /dev/null -w "%{http_code} " https://localhost:9443/get \
-o /dev/null -w "%{http_code}" https://localhost:9443/get
```
f. Check `error.log`
```

```
However the proposed solution didn't seem to fix the issue in my case. I
still get the same errors.
```
tablepool.release("tracing", tracing)
ctx.tracing = nil -- add this
```
