pq_recvbuf: unexpected EOF on client connection

Hello, I am new to the list and have a question. I am trying to get Horde/IMP and pgsql working together and am getting the following error:

pq_recvbuf: unexpected EOF on client connection

looking at stout shows:

This repeats 8 or 9 times until Apache stops trying to load the page.
I have done a Google search to try to find the answer but only find others with a similar question. If anyone can point me in the right direction I would greatly appreciate it.
