            <title>[MC-3934] Particle overload when returning from AFK</title>
                <link>https://bugs.mojang.com/browse/MC-3934</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;I built an village in The End by transporting two villagers through the portal. I locked them in a 4x2 area surrounded by 92 valid doors. I positioned myself at the top of the wall watching the villagers.&lt;/p&gt;

&lt;p&gt;I left the computer for ~3 hours. When I returned the screen was blanked (like normal.) It was slow to resume and minecraft was very laggy. After a while all heart particles that had been generated during my AFK period appeared at once causing the game to reach an almost complete halt.&lt;/p&gt;

&lt;p&gt;I logged out to remedy the issue. All subsequent reconnecting attempts failed because the client timed out. The server logs stated:&lt;/p&gt;

&lt;div class=&quot;code panel&quot; style=&quot;border-width: 1px;&quot;&gt;&lt;div class=&quot;codeContent panelContent&quot;&gt;

2012-11-28 17:34:27 [INFO] Disconnecting Banemannen [/192.168.1.2:58264]: Took too &lt;span class=&quot;code-object&quot;&gt;long&lt;/span&gt; to log in
&lt;/pre&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;Restarting the server and getting another player to the spot made logging in working again.&lt;/p&gt;

&lt;p&gt;Update: It also seems to apply non heart particles like my Iron golem lava trap. It&apos;s 3x3x3 where the bottom layer is water, second layer is signs and the third layer is lava. The Iron golems are dropped from above into this pit. I left the game running for a couple of hours and when I came back my iron ingots were displaying 8 and the game moved at something like 0.2 FPS. I struggled to move away 16 blocks (because I thought that to be the border where particles disappear) then I logged logged out and back in. This time relogging worked and I could continue as usual. Note that all this is done on a vanilla SMP server.&lt;/p&gt;</description>
