Merge Agents Don't "Retry" After SQL Server Error 8645?

During a memory- and CPU-intensive nightly database update process, the
merge agents (running on the server) for two subscribers failed with
SQL Server Error 8645 (A time out occurred while waiting for memory
resources to execute the query). It's not surprising to see this error,
but the fact that the agents did not retry as configured is surprising.
I discovered that this message is listed as a "severity" of 17 - is
there some threshold that prevents a retry by the agent? A restart of
the agent was successful.

How many merge agents do you have? Are you limiting the number of concurrent
merge agents?

|||There are only two subscribers, so two merge agents with no concurrency
limit configured. I'm not so concerned about the error as long as a
retry happens as configured.
