Which version of HDF5 are you using? Would you be able to send me a small program or code snippet and a sample file to reproduce the issue? A similar issue came up a while back (pre-HDF5-1.8.5) with a netCDF-4 user, but we never determined what the issue was.
You can place the files on our local ftp server. Let me know (at help@hdfgroup.org) when they are there.
Here are the instructions:
···
---------------
ftp ftp.hdfgroup.uiuc.edu
Login as "anonymous"
Go to the pub/incoming/help/ directory:
cd pub/incoming/help
Type 'pwd' to see if you are in that location. (You will not be able to see the contents of
the directory.):
pwd
Type 'bin' to put in binary mode:
bin
Place file in directory after you are in binary mode:
put xxx
I've place a datafile A2003061013500.L2_LAC_AT110 on the ftp server as well as a routine compress_memleak_multifiles.c that I hope will demonstrate the problem.
It is actually a netcdf4 file but the HDF5 library is called to do the reads and the example program uses only HDF5 calls.
It simulates multiple files by opening the same one five times. The allocated memory leak is about 15M.
We are using hdf5-1.8.10-patch1.

Thanks, Joel! I have your files and will take a look.
