[pgpool-general: 5222] Node status mismatch on primary/secondary (status 0?)

[Jeremiah Penery]

PGPool-II 3.5.4, streaming replication mode.  Everything seems to be working correctly - Postgres replicating properly, standby not behind primary, no errors in either PGPool or Postgres logs, on either primary or standby.

The primary reports:

=> show pool_nodes;
 node_id |   hostname   | port | status | lb_weight |  role   | select_cnt
---------+--------------+------+--------+-----------+---------+------------
 0       | host0        | 5433 | 2      | 0.500000  | primary | 4183
 1       | host1        | 5433 | 0      | 0.500000  | standby | 0
(2 rows)


The secondary reports:

=> show pool_nodes;
 node_id |   hostname   | port | status | lb_weight |  role   | select_cnt
---------+--------------+------+--------+-----------+---------+------------
 0       | host0        | 5433 | 2      | 0.500000  | primary | 8
 1       | host1        | 5433 | 2      | 0.500000  | standby | 0
(2 rows)


I've tried restarting (both nodes), deleting the status file(s), reconfiguring, and several other things, but no matter what I do, the primary reports that node 1 is in status 0.
Why does this happen, and what can I do to fix it?

Thanks,
Jeremiah
