Ticking Entity?

[Top_ARO]

I've recently been playing a modified version of FTB Unleashed. I added gregtech, and downgraded Industrialcraft2 to fix the energy grid. I started some mob farming, and whenever the farm is running I have a high frequency of game crashes. Most of them are either ticking entity, rendering entity, or unknown error. I'm using t5 soul shards to spawn a variety of mobs in a room which has MineFactory Reloaded Grinders placed aprox every other block to keep up with the number of spawned mobs. I'm noticing that both my player and random mobs in the area teleporting short distances randomly. Can anyone help me out?

Thanks!
Edit: Actually, that cant be the issue, seeing as how it was several days before Halloween that I was having the issue. And my crash report didnt look like the one posted there. I was getting ticking entities from all sorts of different mobs. Passive, hostile, player... I guess I'll just classify this as "things to work around". But ever since I stopped using the MFR Grinders, I have ceased to run into this issue.
