It's a system error, I quote from man 2 intro

---------------------------------------------------
55 ENOBUFS No buffer space available. An operation on a socket or pipe
was not performed because the system lacked sufficient buffer
space or because a queue was full.
---------------------------------------------------

which sounds like you're running low on system resources,
is the box thrashing itself ot death when you get this error?

(Take this off-list if you want as it sounds system related, not
application-specific)
