Yeah, there is no mechanism that would wait within a transaction for a parent
to become available again. Within a transaction when a parent is marked down,
ATS will try to select another available parent to complete the transaction or
go direct to the origin if the config allows it. The closes
Hi John,
Ok, that’s what I thought.
It’s the 502s that I’m trying to avoid in this instance.
As far as I can tell, the retry mechanisms on a parent do not support any kind
of “back off” mechanism, so you can have 100+ retries, but with an offline

No a parent is not retried within the same transaction. If the configured
number of retry counts is not exceeded, another parent would be chosen if there
are other available parents. If there are no other available parents and the
configs allow it, the transaction may go direct to the origin,

would like to know if there is way to configure a “sleep” between connection
retries on a particular parent?
The ability to configure the “connection attempts” is not useful here, as when
the parent is completely o
