Bug Report

We are tracing our application which communicates with postgres via the asyncpg driver.
Everything works perfectly in ddtrace==2.17.3 which we are currently using, but upgrading to 2.18.1 results in our asyncpg driver constantly timing out, for example:

/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/sqlalchemy/engine/default.py:621: in connect
    return self.loaded_dbapi.connect(*cargs, **cparams)
/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/sqlalchemy/dialects/postgresql/asyncpg.py:953: in connect
    await_only(creator_fn(*arg, **kw)),
/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/sqlalchemy/util/_concurrency_py3k.py:132: in await_only
    return current.parent.switch(awaitable)  # type: ignore[no-any-return,attr-defined] # noqa: E501
/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/sqlalchemy/util/_concurrency_py3k.py:196: in greenlet_spawn
    value = await result
/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/ddtrace/contrib/trace_utils_async.py:35: in wrapper
    return await func(mod, pin, wrapped, instance, args, kwargs)
/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/ddtrace/contrib/internal/asyncpg/patch.py:103: in _traced_connect
    conn = _TracedConnection(await func(*args, **kwargs), pin)
/opt/virtualenvs/api-NPeSkiFo-py3.12/lib/python3.12/site-packages/asyncpg/connection.py:2420: in connect
    async with compat.timeout(timeout):
/usr/local/lib/python3.12/asyncio/timeouts.py:115: in __aexit__
    raise TimeoutError from exc_val
E   TimeoutError

Reproduction Code

So far I was not able to create a small reproducible example, this happens after the process runs for a while, performing many different DB queries. Will continue trying.

Error Logs

We're getting the following debug log from the tracer when the issue occurs:

DEBUG    ddtrace._trace.tracer:tracer.py:877 span <Span(id=16630326685907300418,trace_id=137532420521718859218382865815756886327,parent_id=12504371964807139896,name=api.http.request)> closing after its parent <Span(id=12504371964807139896,trace_id=137532420521718859218382865815756886327,parent_id=None,name=http.request)>, this is an error when not using async
