I forgot to mention in my original message that I'm running Dovecot
2.3.21 (47349e2482).
It seems like the stalls are more likely to happen
when the type of sync is "incremental" rather than
"normal" or "full".
(I'm inclined to think they only happen for incremental syncs,
but I'm not sure.)

I have two Dovecot mail servers that replicate to each other.
Sometimes there are delays in the synchronization,
and I notice that the mail log has entries like this:
Error: dsync(spokane): I/O has stalled, no activity for 600
seconds (last sent=mailbox, last recv=mailbox_state)
Five minutes seems like a long time to sit there waiting with
nothing happening.
Is there a way to reduce this timeout so that I don't have so many
replicaton connections just sitting around doing nothing?
(Of course, a way to prevent the I/O stalls would be great too,
but with my limited upload bandwidth, they may be unavoidable.)
