hi there.
we have rent a rather powerful vserver.
CPU and Ram usage is at 20-30%, so this can't really be the problem.

my console says:
[002:37] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 7819ms behind, skipping 156 tick(s)
[003:37] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 16623ms behind, skipping 332 tick(s)
[004:13] [Server thread/WARN]: Can't keep up! Did the system time change, or is the server overloaded? Running 2653ms behind, skipping 53 tic
so the server itself is not overloaded. minecraft/java has 17GB Ram availalable and more than enough CPU power.

is there a way to stop/prevent that kind of lag?
or ... is there a way to find out WHY the server is lagging like that?
the only thing we did before the lags started, was starting our applied energistics system. but we already removed it and it didn't stop the lags

solved it,
originally, we were planing to play agrarian skies. which (at least what my friend said) doesn't run on Java 8.
so he installed Java 7.
then we decided to play agrarian skies 2 instead. so we ran it on Java 7.
it worked.
but after a while, we had the problem reported above.
now after using java 8 instead, the server is running perfectly fine :)
