<p>Hi Bilel,</p>
<p>That's surprising for sure. We hit that condition once before
(see <a class="moz-txt-link-freetext" href="https://github.com/darshan-hpc/darshan/issues/243">https://github.com/darshan-hpc/darshan/issues/243</a>) locally
and added that message as a replacement for an assertion in case
we encountered it again, but we never figured out how to reproduce
it.</p>
<p>Has Darshan itself been recompiled since the upgrade? This
warning is emitted by the Lustre instrumentation module. It's
plausible that something changed in the Lustre library API that's
causing some runtime incompatibility.</p>
<p>thanks,</p>
<p>-Phil<br>

get such warning…
