As by this OpenWRT bugreport:
https://dev.openwrt.org/ticket/20038

On various architectures – at least a mips and powerpc one – nfs-utils 
is broken with musl, yielding a never ending stream of "my_svc_run() - 
select: Bad file descriptor" in the system log.

The message originates in the this file:
http://git.linux-nfs.org/?p=steved/nfs-utils.git;a=blob;f=utils/statd/svc_run.c

"Downgrading" to uClibc has the issue vanish.

I verified this myself with recent git versions of both musl and the 
utils on a fresh ar71xx OpenWRT compilation.
