[pgpool-general: 839] Pgpool - not more connection than 80

[Albert]

Hi,

I test a pgpool 3.1.3 now with one DB PostgreSQL 9.1 server and when I 
run our jmeter test I have only max 80 loggen-in users. In pgpool I get 
some errors:

2012-08-02 14:44:02 ERROR: pid 9743: pool_read: read failed (Connection 
reset by peer)
2012-08-02 14:44:02 LOG:   pid 9743: ProcessFrontendResponse: failed to 
read kind from frontend. frontend abnormally exited

The target configuration, I would like to connect an additional 2-3 
servers with streaming replication.
