Indeex, I used the numbers from RH6. Yeah, min/max change based on the <br>
distro, sigh. Anyway, some thread is unblocking these signals.<br>

&gt; Xrootd does not use SIG 64 and SIG 63, it uses SIGRTMAX and SIGRTMAX - 1 :)<br>
&gt;<br>
&gt; On fedora 30 these are:```<br>
&gt; root [2] SIGRTMIN -&gt; (int) 34<br>
&gt; root [3] SIGRTMAX -&gt;(int) 64<br>
&gt; root [4] SIGRTMAX - SIGRTMIN -&gt; (int) 30<br>
&gt; ```<br>
&gt; so `SIGRTMAX - 1 = SIGRTMIN + 29`.<br>
&gt;<br>
&gt; How about a plugin using signals and not blocking the RT signals (or unblocking them through ignorance) so they get delivered there from XRootd AIO code, even though they should not? Although I must admit I can not imagine the mess when signals are used for internal communication by two different sub-systems in a single multi-threaded program :)<br>
