Hi Krzysztof, I'm not expert of FreeBSD: can make sure the SO allows to set up a pipe of plugin_pipe_size? On Linux you would do it by touching the files /proc/sys/net/core/[rw]mem_max. Also, if you could check out the pmacct release currently in the CVS it behaves differently from the past where: upon not being able to get the requested memory, it asks the SO for the default size (not doing so, at least on Linux, returns a very minimal amount).
Also, since you say this is only happening on one of the systems, does this system have anything specific than others? Is the issue presenting at peak hour or, generalizing, can it be correlated to a transient high volume of traffic?
