Is your server an NFS server?
Normally nfsd is the name of the NFS daemon.
The NFS clients can stress it, then it consumes more CPU.

NAME
rpc.nfsd - NFS server process SYNOPSIS
/usr/sbin/rpc.nfsd [-p port] nproc DESCRIPTION
The rpc.nfsd program implements the user level part of the NFS service. The main functionality is handled by the nfsd.o kernel module; the user space program merely starts the specified number of kernel threads. The rpc.mountd server provides an ancially service needed to satisfy mount requests by NFS clients. OPTIONS
-p port specify a diferent port to listen on for NFS requests. By default, rpc.nfsd will listen on port 2049. nproc specify the number of NFS server threads. By default, just one thread is started. However, for optimum performance several threads should be used. The actual figure depends on the number of and the work load created by the NFS clients, but a useful starting point is 8 threads. Effects of modifying that number can be checked using the nfsstat(8) program. SEE ALSO
rpc.mountd(8), exportfs(8), rpc.rquotad(8), nfsstat(8). AUTHOR
