Strangest FTB Server Problem

[NoOpen]

I am trying to run a dedicated server with a slightly modified monster pack, If I have a dedicated world and connect to it, There are 500+ entities and I have considerable FPS lag, I have set it to peaceful and tried /cofh kilall and the number remains around the same. Oddly when I press T (To open a chatbox) or go to the escape menu my entity count drops to below 100 and my FPS is fine, Also a singleplayer world has below 200 entities and perfect FPS.

This problem occurs on other computers, other networks, with all mob centered mods removed, and fresh installs of aforementioned pack. The problem does not occur when opening a singleplayer world to lan, I am on 1.6.4

Any help will be greatly appreciated.

EDIT: I have rounded the problem down to Ars Magica 2 the latest version for 1.6.4. Still not sure how to fix

Go to the AM2 configs and disable Hecates. IIRC there's a bug with them where they will not despawn properly. Set their spawnRate to 0.

Also, if you have Openblocks installed, add hecates to the additional section in the config like so:

additional { # List any mob names you want disabled on the server S:disableMobNames < arsmagica2.MobHecate > }

also, if ou haven't already, update rieka's mods to 25z.

Sadly that did not fix it, Also yes my Riekas mods are at version 25z.

What's OPIS reporting for the entities?

Oddly enough Opis cant see them, They also rise if I let it go well into the thousands.

/cofh killall should say what kind of entities they are.

/cofh killall does not get rid of aforementioned entities

 

[Qazplm601]

huh. hmmm. how are you detecting them?

There was noticable lag in my server, So after much trial and error I noticed with Ars Magica 2 Installed on a dedicated server the entity count (As shown by the default F3) was very high and the rest is in my first post

Try /cofh killall hecate. It's been a while, bit I seem to remember how ars magica mobs don't respond to just /cofh killall

No good

If OPIS isn't even showing the entities, I'm highly doubtful there are that many.

So how do you explain my problem only occurring with Ars Magica 2 and when the entity count is quadruple plus on a dedicated server.

Not trying to be conceded actually curious

AM2 is notorious for causing performance problems, and that's without its entities spawning uncontrollably. OPIS will, however, show all of the entities. And since it isn't showing a massive amount, it sounds like the entity counter either is finding something OPIS isn't configured to, or that it's broken.

Hmm okay, Still very confusing why it only happens when the server is dedicated.
