Ok, so simple read, double check you removed previous mods from the mod folder, looks like you just pasted mods into the server instance and it now has two or more of the same mod.Use version 2.1.4
here some crash reports....

http://pastebin.com/5tmMrvrJ <--- After this crash report it, then ultimately to real crash.
Log Files:

There are more Logs, but I can´t post it because they are to big..... they have over 10 MB
The strange thing: The server creates these crash reports while he powers up in Minutentackt and then lubricated after about 45 minutes from final.
He produced every 60 minutes good 100MB of log files, which is not really great for a server with only 5BG HDD
I'll report it to botania, but after recent announcements not sure if it will ever get fixed....v 2.2.1
@GreatOrator I've confirmed that the accumulation of lag-causing 'ghost' entities with the life imbuer from Botania occurs with this version of the modpack as well. It is not caused by either the Optfine mod and/or the Spax texture pack (ie I removed both and it still occurred) as you can see in the screenshot below. The only way to clear these 'ghost' entities and resolve the lag is to save and quit to title and reload the save. Then remove the life imbuer so it doesn't happen all over again.
The accumulation in the screenshot below is from about a half an hour away from the immediate area of the spawner to which I attached the life imbuer.

While I'm all for prettiness, I also vote for functionality over visuals.
@Vals NoisyToys had updated the process for updating the modpack when there is a content update for anyone who needs help. Thank her in any way you can for her hard work!
