Tomcat+JDBC application connecting to PostgreSQL via pgPool II version
3.3.0, installed from RPM, in Master-Slave load-balancing mode
(streaming replication, 1 replica).  pgPool query caching is turned off.

Currently we're getting repeated errors like this every few minutes on
Tomcat: "An I/O Error occurred while sending to the backend."

No errors show up in the PostgreSQL logs.  As soon as the client clears
them, I should be able to send you pgpool debug logs (offlist).  The
problem is 100% reproduceable.
