[pgpool-general: 3556] Upgrade from 3.3.1 to 3.3.3

[James Sewell]

Hey All,

We have upgraded PGPool node to 3.3.3 (from 3.3.1) and tested, but we are
hitting an error.

PSQL access through the node hangs after an amount of time (as low as 40
minutes, the highest overnight). Has anyone struck this before?

We had debug mode turned on, but the logs do not seem to show any errors
except for those shown below. These errors appear to have been happening
when PSQL access was working.

2015-03-20 08:24:47 DEBUG: pid 17173: health check: clearing alarm
2015-03-20 08:24:48 LOG:   pid 17207: send_failback_request: fail back 0 th
node request from pid 17207

2015-03-20 08:24:48 DEBUG: pid 17173: failover_handler: starting to select
new master node
2015-03-20 08:24:48 ERROR: pid 17173: failover_handler: invalid node_id 0
status:2 MAX_NUM_BACKENDS: 128

While I can't access the backend servers through PSQL PCP commands are
still responsive.
