I don’t have much experience with ITK_USE_THREADPOOL enabled. I believe it is still labeled experimental. Does this problem occur if this feature is disabled?

<div>Thanks for your answer. The program execution is on my lab cluster, running Fedora 24 and PBS for job scheduling. I did not see any such limit but I'm probably missing something. Note that the programs seem to run with ITK_USE_THREADPOOL=ON.<br>

<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>
