Perhaps your NFS server is too slow, and NFS requests are backing up?
See if dmesg reports "NFS server not responding".  Make sure DMA
writes are turned on on your NFS server.

If your database is still local to the backend, maybe the markup
writes are backing up?  I can't believe this is the case since that
shouldn't be that much data; but you might want to *try* to reduce
/proc/sys/vm/dirty_writeback_centisecs to 100 and see if that fixes
the problem.

Cheers,
Kyle
