Currently the test passes, but may fail during shutdown, because blocks and transactions are synced with NUM_INBOUND * self.num_nodes peers, which may take a long time.
There is no need for this test to have this amount of inbounds.
So avoid the extraneous inbounds to speed up the test and avoid the intermittent test failures.

It looks like 29926 is adding a call to setmocktime in the test. As the issue happens after all tests have passed, this can not fix the issue. Or am I missing something?
To explain it a bit more, the traceback is:
0 File "/test/functional/p2p_tx_download.py", line 302, in <module>
1 TxDownloadTest().main()
2 File "/test/functional/test_framework/test_framework.py", line 155, in main
3 exit_code = self.shutdown()
4 ^^^^^^^^^^^^^^^
5 File "/test/functional/test_framework/test_framework.py", line 314, in shutdown
6 self.network_thread.close()
7 File "/test/functional/test_framework/p2p.py", line 732, in close
8 wait_until_helper_internal(lambda: not self.network_event_loop.is_running(), timeout=timeout)
9 File "/test/functional/test_framework/util.py", line 293, in wait_until_helper_internal
10 raise AssertionError("Predicate {} not true after {} seconds".format(predicate_source, timeout))
11AssertionError: Predicate ''''
12 wait_until_helper_internal(lambda: not self.network_event_loop.is_running(), timeout=timeout)
13''' not true after 10.0 seconds
Which is after the test has passed successfully.
To get the full error log on Cirrus CI, you’ll have to use the “Open Full Logs” button to see the full log. Usually the output is:
… (dots from the test runner) traceback (from the failed test) Full combined logs (from the failed test) Full test summary (from the test runner)
self.shutdown() traceback in this one: https://api.cirrus-ci.com/v1/task/6740372997537792/logs/ci.log
I can see the

Thanks, in this case it seems the issue is transactions relayed to the extraneous peers. I’ve edited the pull request description.

fill_mempool function causing the sync timeout specifically. Can a note be left here to say why we’re not making additional inbounds?
I think the real reason would be “because they are not needed”. The secondary reason would be that the test will be faster on slower hardware. The final reason would be that this avoids intermittent test failures/timeouts. However, there are other ways to avoid the intermittent test failures, so I am not sure if this is the right place to document it.
Should I just put a comment here # Avoid inbounds because they are not needed and slow down the test?

not really, doesn’t add anything, so leave it as is
makes sense
