There's a FD leak in gethostbyname(3) in multithreaded programs (actually, in the uthread wrapper for kevent(2), but gethostbyname(3) is the most common reason you'd see it) which was fixed in -CURRENT for programs linked with libc_r.so, but not for those linked with libc_r.a. See PR bin/58687 <http://www.freebsd.org/cgi/query-pr.cgi?pr=bin/58687>. This has a patch available. -- Jonathan Lennox lennox at cs dot columbia dot edu
