rsync and locking

Hello,
I got an issue with rsync and (fcntl) locked files.
When rsync tries to sync a file that is opened and locked by another
process (that use fcntl write lock), it ends up in Disk Sleep.
Then i need to reboot to remove that dead processes (let me now if
there's another solution).
Is there a way to force rsync to skip locked files ?
Here are some facts:
Hosts on which this issue has been verified:
i686 linux kernel 2.2.14 -> 2.2.22
