As you can see, we lose a connection and then try to read from it (FD 40). This is where the log ends because the assert triggered.

Printing the connection struct shows it is actually an issue with FD 26:

The previous connection on FD 26 shows:

[then nothing for a long time until]:

[slapd crashes]

The consumer here in conn 335 is a refreshAndPersist consumer. Not entirely clear why it's connection gets closed.
