nfsserver actually uses your distribution init script:

nfs_init_script (string, [/etc/init.d/nfsserver]): Init script for nfsserver
    The default init script shipped with the Linux distro.
    The nfsserver resource agent offloads the start/stop/monitor
work to the init script because the procedure to start/stop/monitor nfsserver
varies on different Linux distro.

It looks like you need to report a bug to your vendor for the
NFS server init script.

Thanks,
