[SOLVED] "Silently" catching entity tracking error - Console Spam/Lag

Posted February 24, 201510 yr

Hello all!

I have a fun one here... I'll try to provide as much information as possible...

# Problem:

## Server console is being spammed by this error: http://pastebin.com/9kMWU5KG

[server thread/ERROR]: "Silently" catching entity tracking error.

# I have not installed either ModLoader or MCPatcher.

# The client OR server IS NOT cracked.

# Research:

## Found this "related" post in the forums here:

http://www.minecraftforge.net/forum/index.php/topic,27644.msg141768.html#msg141768

### No "fix"/help listed there...

## Also, found this "related" issue with ExtraUtilites:

http://forums.technicpack.net/topic/115546-silently-catching-entity-tracking-error-what-to-do/

### So, I removed all 5 of our EnderThermic Pumps AND chunk loaders from the Nether, and still having console spam.

## Also, noticed a massive amount (6,000+) of Wither Skeletons spawning in the Nether, regarding this "related" issue with Ender IO:

https://github.com/CrazyPants/EnderIO/issues/1899

and

https://github.com/CrazyPants/EnderIO/issues/1958

and

https://github.com/CrazyPants/EnderIO/issues?q=wither

### So, I have updated Ender IO and Mekanism to:

EnderIO-1.7.10-2.2.8.349

Mekanism-1.7.10-7.1.2.179

MekanismGenerators-1.7.10-7.1.2.179

MekanismTools-1.7.10-7.1.2.179

### Updating these mods also did NOT fix the console spam.

# Pack history:

## This is a custom made modpack, by myself. The modpack was origianlly mirrored from ModSauce 1.0.1.1 (mods and configs), then I started to removed/add mods.

## The world file is also brought over from our ModSauce 1.0.1.1 server. Not sure if this is causing any console spam/chunk loading issues.

## This custom modpack has gone through many changes (too many to list) since I have taken it over, and only recently have I been running into this Console Spam Issue. For those interested, the custom modpack changelog is here: http://www.technicpack.net/modpack/zitcraft.581606/changelog

# Summary / TL;DR:

## I am having Console Spam errors, causing 100% CPU & RAM useage, and lag spikes every 10-15 seconds. As far as I can tell it's from a chunk loading/entity tracker error somewhere.

Thank you all for any/all help regarding this matter!

If you would like any more information, please ask! I am more than willing to provide whatever information is requested!

Cheers!

Found & fixed the problem...

I had to change the Ender IO config for Wither Skeletons (from TRUE to FALSE) on line 786 of EnderIO.cfg:

replacewitherskeletons {

# Separates wither and normal skeletons into different entities, enables the powered spawner to treat them differently [EXPERIMENTAL - MAY CAUSE ISSUES WITH OTHER MODS]

B:Misc=false

}

Thank you so much! If you hadn't practiced proper internet etiquette I would have looked for hours for the problem if I even found it at all!

This just literally saved me a ton of time too. Although I also had another issue with wither skeletons...

[22:16:43] [server thread/INFO]: [J0nis: Removed 19634 entities. (§c1§fx§eSkeleton§f, §c19633§fx§ewitherSkeleton§f)]

Put false for: replacewitherskeletons and got rid of this:
