[pgpool-general: 5076] Getting EOF encountered with frontend

[Yates, James C. -ND]

With PgPool 3.5.4 and Postgres 9.5.4.   I’m seeing ERROR(s) like the following, without SSL turned on:

2016-10-26 16:01:27: pid 5896: ERROR:  unable to read data from frontend
2016-10-26 16:01:27: pid 5896: DETAIL:  EOF encountered with frontend
2016-10-26 16:01:27: pid 5896: LOCATION:  pool_stream.c:261


With SSL turned on I see the following:

2016-10-25 10:30:26: pid 19075: WARNING:  ssl read: EOF detected
2016-10-25 10:30:26: pid 19075: ERROR:  unable to read data from frontend
2016-10-25 10:30:26: pid 19075: DETAIL:  socket read failed with an error "Success"


Eventually PgPool stops responding and I have to restart Pgpool.   This is a two node Master/Slave on Redhat EL 6.

I don’t see any errors in the Postgres Database log for these times,  PgPool is running on both of the Database Servers.
