<div>Where is the program execution when the thread being created?</div>

<div>It could fail if the environment has a limit on the number of threads/processes that can run ( i.e. some ulimit like seeing ).</div>

<div>Dear all,<br>
</div>
I have been fighting for a couple of weeks to have ITK-based software (in this case
<a href="http://openrtk.org/" target="_blank">RTK</a>) run properly after an upgrade of our cluster to Fedora 24 (where our nightly tests are run). These are tests that are running well on other platforms. We have finally found a lead: for a reason that we don't understand,
pthread_create fails.<br>
First, ITK does not handle correctly this situation. I have <a href="http://review.source.kitware.com/#/c/21935/" target="_blank">
submitted a patch</a> for this.<br>
</div>
My question is : does anyone know why a pthread_create would fail and is there any solution? This is the first time that I see such a behavior.<br>
</div>
Thanks in advance for your help,<br>
</div>
Simon<br>
