[BProc] bproc: connect... error=11

[Nicholas H. <he...@se...>]

Hey Erik,
	I am running the 2.4.18 with bproc 3.2.5 ( and additional patch ) here.

Here is a link to the syslog from the head node -- it seems we get a ton
of bproc: connect errors. There are also unknown FD errors -- below is a
sampling of what we are seeing.

 Is this some sort of odd network problem, or is this a bproc problem?
