SunOS 5.8 NFS server mounted by linux 2.4.20 client Locking problem

[Rob Heise (rheise)]

Any one have a good idea whats going on here:
 
open("/usr/SD/tibco/jms/3.1.2/bin/datastore/meta.db",
O_RDWR|O_CREAT|O_LARGEFILE, 0666) = 7
fcntl64(7, F_SETLK64, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0},
0xbfffe550) = -1 ENOLCK (No locks available)
close(7)                                = 0
 
rpc.lockd and statd are running.  
 
Thanks in advance
Rob
