Then, probably, I reported the same thing twice. Sorry. I failed the
whole try on the Sarge. But at one time, I passed the tests in the HDF5
package on the OpenSCE(RedHat based distribution for clusters). On the
OpenSCE, I used MPICH 1.2.5 configured with those options. I have no
idea about the failure on Sarge.
Okay. I would like to be sure that the change you requested fixes the
problem before applying it, so I'd appreciate if you could verify this
at some point.

I didn't test the options on 2.2 kernels. But the HDF5 installation
manual says that those options will work only on kernels 2.4 and
greater. So, I'm not sure that those options cause any side effects or not.
I see. Well, when we've determined that it works for 2.4, I can test to
make sure this doesn't break all of mpich under 2.2. If everything
except large files works under 2.2, then that's not at all a showstopper
for uploading the fixed package.
Thank you,
