persistent_connections_limit
The maximum # of simultaneous persistent connections to remote persistent agents. Each time connecting agent defined under 'agent_persistent' we try to reuse existing connection (if any), or connect and save the connection for the future. However we can't hold unlimited # of such persistent connections, since each one holds a worker on agent size (and finally we'll receive the 'maxed out' error, when all of them are busy). This very directive limits the number. It affects the num of connections to each agent's host, across all distributed indexes.
It is reasonable to set the value equal or less than max_children option of the agents.
Example:
persistent_connections_limit = 29 # assume that each host of agents has max_children = 30 (or 29).
