Nevermind! Found it.

The file ID for the patch is 17637. Do you know the bug number? I’m wondering if it is fixed in 7.3.2
Just mentioning it here because hard work deserves to be recognised and mentioned: Andrew McDonnell is doing an awesomely good job of testing, understanding and fixing bugs in OQGraph... which is no mean feat because the core of the code is based on the Boost Graph Library which isn't a trivial C++ library.
Back in my days at MySQL we had a lot of issues with test
failures. We had lots of platforms, and would try to run and
maintain our regression test suite on all of them. I remember
spending days investigating issues on some obscure OS (Mac OS,
mainly, Windows was taken care of) or hardware (little-endian,
mainly) .
With Tarantool, we never got to do that. We do run buidls on lots
of platforms, and someone always screams when they break, since
we only run builds on platforms which are in actual use. And they
do break, so it's a lot of hassle. But we haven't had time to
maintain the regression tests on some of these platforms. Ugly?
Yes. Yet we know which systems people use in production, and do
take care of these. This set is much more narrow than the set of
systems which people play with.
And also, we don't pay attention to test failures caused by,
essentially, bad tests. If a test fails once in a while on a busy
box, well, this is kind …

Working day to day with Percona Remote DBA customers, we have been facing an issue from time to time when MySQL replication lag is flapping between 0 and XXXXX constantly – i.e. Seconds_Behind_Master is 0 for a few secs, then it’s like 6287 or 25341, again 0 and so on. I would like to note the 5 different scenarios and symptoms of this – some are obvious and some are not really.
1. Duplicate server-ids on two or more slaves.
Symptoms: MySQL error log on a slave shows the
slave thread is connecting/disconnecting from a master
constantly.
Solution: check whether all nodes in the
replication have unique server-ids.
2. Dual-master setup, “log_slave_updates” enabled, server-ids changed.
Scenario: you stop MySQL on the first master, then you stop the second one. …

The journey is old, but the milestones are new. It’s the same old
quest for excellence. Innovative questions are being asked and
answered in the blogs across the Oracle, SQL Server and MySQL
branches of technologies. This Log Buffer Edition relishes just
that. Let’s start this Log Buffer with the exquisite blog post by
Dana Pylayeva.
Oracle:
EMlight might not be as important now with Oracle 12c coming out and with Oracle’s EM Express, but EMlight is still pretty cool.
The maximum size for VARCHAR2, NVARCHAR and RAW columns has been extended to 32767 bytes with the Oracle …
