Bukkit

Okay, simple. When I enable this plugin, my console keeps spamming: [Server] WARNING Can't keep up! Did the system time change, or is the server overloaded?
I tried with iConomy 6 & BOES, happens to both. I got following plugins:
LWC
Dymap
Repeat
iConomy 6
Jail
Essentials (Core only)
Bycraft

That's it.
I got 512MB ram (which should be enough). Also, my server got like 1-2 second delay when you attack, flip a lever or chat. (Which normally is instant).

Else - It's working as it should.

Happens when there is a slow connection to mysql server, the mysql database hosts? I recommend hosting the mysql on the same server as minecraft.

Okay thanks, I'll tell my host to make a MySQL DB for me :)

We are actually doing something about the java files that should improve this. Will be released soon.

Try v0.6.2 to see if it reduces the lag at all.
