<p>Hello Jack,</p>
<p>the proper venue could be the Foojay.io forums [1] (yes, only
recently created) or #crac channel on Foojay slack, but this list
will do :)<br>
</p>
<p>Can you try running the checkpoint with
`-XX:CRaCIgnoredFileDescriptors=/var/lib/sss/mc/passwd` ? This
should bypass the checks, though problems may arise on restore if
this file changes when the application is in checkpoint.</p>

I am attempting to checkpoint my application but I get an
exception saying that /var/lib/sss/mc/passwd is open:

<div>The only thing I've found mentioning a similar issue is
this old thread: <a href="https://mail.openjdk.org/pipermail/crac-dev/2022-January/000079.html" moz-do-not-send="true" class="moz-txt-link-freetext">https://mail.openjdk.org/pipermail/crac-dev/2022-January/000079.html</a></div>

</div>
<div>The workaround posted there involves system-level
configuration changes, but I am an unprivileged user on a
shared RHEL8 machine so cannot apply such a workaround.</div>
<div><br>
</div>
<div>Is there anything I can do to resolve or at least
workaround this issue?</div>
<div><br>

<div>Cheers,</div>
