Re: No such file or directory in pg_replslot

I don't know if this applies only to pglogical or logical decoding in general. This is on a 9.6.10 provider running pglogical 2.2.0. Subscriber has same versions. We had a replication delay situation this morning, which I think may have been due to a really long transaction but I've yet to verify that.
I disabled and re-enabled replication and at one point, this created an error on start_replication_slot that the pid was already active.
Somehow replication got wedged and now even though replication appears to be working, strace shows these kinds of errors continually:

Any suggestions? This is a showstopper for us.
Thank you,
Jeremy
