Hello everyone in the list, testing pgpool a failover is triggered but the
master is running. The pgpool version is 3.5.5. This is the log reported by
pgpool.
Could anybody help me to clarify this error?
The reason could be postgresql server has reached max_connections?
Regards.

Yes, it seems process 5479 hit the max_connections of PostgreSQL while
connecting to it.

Could be possible to use retries upon Streaming Replication Check for
preventing failover when connections to master fails?

Retrying is not possible, but by setting fail_over_on_backend_error to
off, you can avoid failover.
