We are using pgpool-II 3.3.3 with 4 nodes of Postgres 9.3.
At some point today 2 of the 4 nodes had errors and pgpool did a successful
When the 3rd node had errors pgpool also reported a successful failover but
clients could not create connections. For a few hours the pgpool log
contained such messages:

2014-09-23 03:03:15 ERROR: pid 13408: pool_read_kind: kind does not match
between master(0) slot[0] (52)

And at the same time the last db node had those messages:

db_here 2014-09-23 03:15:47 PDT [22250][user_here]: [1-1] LOG:  could not
receive data from client: Connection reset by peer

Any idea what can cause this behavior?
