I've had a similar problem on our ldm system (ldm 5.0.8, Linux 2.0.36).
All I've been able to figure out is that the growth occurs somewhere in
the ~mcidas directory.  Likewise, our data is written to a separate file
system which is not affected when this occurs.  Restarting the ldm
always seems to fix this problem which, thankfully, does not happen very
often.
