Due to the environment (a very high number of potential NFS servers, all running NFSv3) V4 is not an option. And, as I said, the locking problems occur on local files. NFS is only related to the high-load condition that seems to accompany the locking problems.

Ah, I misinterpreted what you meant. Are there other processed besides the copy of three large files tat might be keeping lots of files open? Have you checked the file allocation limits in proc (/proc/sys/fs/file-nr)? I hear for 2.6 kernels you rarely have to tweak these settings, but it might be worth looking into if you haven't already.
