No, but a very likely reason is that an smbd holding a
shared file is stuck in gfs in state D.

Yep, 4GB is a known limit for tdb, it uses 32 bit pointers
internally. Tridge right now is looking at expanding that.
Search for stuck smbds, reboot those nodes and file a bug
with RedHat. We've had quite a few of those supporting
"wakku" on the #ctdb irc channel the last few days.
You might want to comment out the call to
SMB_VFS_KERNEL_FLOCK() in smbd/open.c, gfs2 seems very
unhappy with that call, leading to processes in state D
