<div style="font-family:Tahoma;font-size:13px">Hi everyone,</div>
<div style="font-family:Tahoma;font-size:13px"><br>
</div>
<div style="font-family:Tahoma;font-size:13px">I've been experiencing a strange issue for a few days now and I didn't manage to solve it yet. There is something wrong with Geoserver's Java threads, as after some usage, the navigation on website suddenly becomes
slow and when executing a "top" on server, I find all CPU cores at 100% and a long list of tomcat8 processes running, even if no one is accessing the site.</div>
<div style="font-family:Tahoma;font-size:13px"><br>
</div>
<div style="font-family:Tahoma;font-size:13px">Unfortunately, checking the logs doesn't give me a clue of what's happening, as warnings and errors are constantly changing and so far I was not able to spot the exact moment when Java failures are triggered.</div>
<div style="font-family:Tahoma;font-size:13px"><br>
</div>
<div style="font-family:Tahoma;font-size:13px">I'm running Geonode 2.7.5, with Geoserver 2.12 snapshot on an Ubuntu 16.04 Server. I already tried upgrading both tomcat8 and OpenJDK from apt, but it didn't solve the issue.</div>
<div style="font-family:Tahoma;font-size:13px"><br>
</div>
<div style="font-family:Tahoma;font-size:13px">These are building infos on Geoserver:</div>

<div><i>Build Information</i></div>

<div><i>2.12-SNAPSHOT</i></div>
<div><i>Git Revision</i></div>

<div><i><br>
</i></div>
<div><br>
</div>
<div>I also tried updating Geoserver version to 2.13, but some layers (defined by SQL queries) stopped working, hence I had to rollback to 2.12.</div>
<div><br>
</div>
<div>This machine has been running fine for months, and only a few days ago started having this issue; we didn't install anything new, so I'm wondering if any of the layers uploaded is somehow causing the problem.</div>
<div><br>
</div>
</div>
<div style="font-family:Tahoma;font-size:13px">I attached an extraction of Geoserver log, hoping this can give you some hints.</div>
<div style="font-family:Tahoma;font-size:13px"><br>
</div>
<div style="font-family:Tahoma;font-size:13px">Thanks,</div>
