Greetings,
I'm currently testing pgpool-3.2.0 in a staging environment.  While
doing so, my IT department decided to perform some sort of security
scan of the servers in my network, including the 3.2.0 server.  When
this happened, I saw the following in the pgpool log:

2012-08-08 09:58:33 ERROR: pid 3595: read_startup_packet: invalid startup packet
2012-08-08 09:58:42 ERROR: pid 2049: read_startup_packet: invalid startup packet

2012-08-08 09:59:09 ERROR: pid 2508: read_startup_packet: invalid startup packet
2012-08-08 09:59:21 ERROR: pid 2549: read_startup_packet: incorrect
packet length (-2139750145)
2012-08-08 09:59:21 ERROR: pid 2549: read_startup_packet: out of memory
2012-08-08 09:59:26 ERROR: pid 2905: read_startup_packet: invalid startup packet

I don't know how to trigger this manually, but it seems like something
that is potentially bad.  I don't understand how a packet can have a
huge negative length, but I'm most concerned that pgpool seemed to
exhaust memory somehow.  Any ideas what is going on here?

thanks
