[Pgpool-general] pgpool disconnecting client

[MA]

Hello list,

    we're new to pgpool, we have a java application running fine while 
connected directly (no thru pgpool) to our postgres servers. The 
application is based on compass-project http://www.compass-project.org/

Now when we try to use pgpool it executes some of the statements but at 
some point it got disconnected, server logs show a "LOG:  unexpected EOF 
on client connection". pgpool log seems not to work although we have 
enabled its options as follows
- log_connections = true
- log_hostname = true
- log_statement = true

Below is a detailed log of one of our database servers included into the 
pgpool, we're using latest jdbc driver. And as I described this same 
application works fine with postgres server when it's connected directly 
to it, not through pgpool

-Is there any chance that this is related with pgpool configuration? 
probably a timeout?
-Is this a bug?
-Can anyone pinpoint into the right direction to have also pgpool log 
all the statements?

Thanks in advance, any ideas are deeply appreciated
