I've been running with this almost identical patch already for some time:

glibc-2.28.

There was a posting by Michael Marley on 31/08 saying he saw something similar to this problem after upgrading to 2.28 as well with 'doveadm purge'.

Hi Aki,

How did you go with this in the end?  Do you need anything more from me or were you able to reproduce this?

Thanks, Reuben
