Hi all,<br>
<br>
since we originally reported the issue, it might make sense to
mention that the IdP producing this error is also running on SLES
(version 11 SP4 if I am not mistaken).<br>
<br>
I checked some other IdP servers we are running and was not able to
find the error in the log of any of them. None of them is running on
SLES. <br>
On the flipside, none of then has a similar load than the one with
the ELException.<br>
<br>
Looking through the logs I would also say that the error is getting
more frequent, but that is hard to say with our small sample size.<br>
We recently started getting some reports from people trying to login
getting the Exception, though, so there's that.<br>
<br>
Some other information about the environment, which is similar to
Brian's:<br>
- JDK 1.8.0_112<br>
- IdP 3.3.0<br>
- Tomcat 8.0.39<br>

<font face="times new roman, serif">For the Apache config on
the IdP server, the ServerLimit and MaxClients were set to
something ridiculous so we could see what kind of load it
could take. On the testing VM we were running out of
ephemeral ports, so we added a registry key to increase the
max port number that could be used by a user: <a

(this is not needed to reproduce the error, but cuts down on
some noise). We did still have some socket errors on the
testing VM, but overall it seemed to run a lot better.</font></div>

</span>A basic "Wait too long" timeout doesn't have anything
to do with this error, so that's as expected. So I have no
idea how one would reproduce it.<br>
