Postfix has a bunch of worarounds for LMDB, that were working by
the time that LMDB support was implemented, but LMDB may have been
'improved', and it may be time to review those workaroundso
In the meantime, you can set a larger limit.

Instead of speculating you could set tls_fast_shutdown_enable to
revert the old behavior and see if it makes a difference.
So I'll wait for that to be confirmed. No need to drop everyting
I am doing.
