Water and Redstone slow motion bug

[gon4zz]

Hi everyone, i have a very annoying bug that keeps coming back to me everytime i host a server.

It makes water and redstone/wires go in slow motion, what i mean is that if i press a button that is connected to redstone it takes about 20 minutes for it to switch itself off, or if i place a bucket of water/lava it runs 1 block every 5-10 minutes. This makes it really annoying since we cannot get any redstone or wires to work properly. Does anyone know what that causes this problem?

I have good enough internet and computer to run a server, we have no lag whatsoever and its only after we played for 10 minutes the slow motion bug starts.. if i restart the server it works fine for another 10 minutes.

any help with this problem will be very appreciated.

I will try to give any info you need to help me fix this:)

Things ive tried so far:

-Changed ram on server from 1gb to 12gb (seems to run better on lower ram)

-Reinstalled Tekkit/server

(Plugins im running: Multiverse, PermissionsEX, Worldsaver)
