Mob's attack speed

[Meridian59]

I'm really confused, sometimes the mobs in my server attack very fast as if they had speedhack, but sometimes they just act normal.

My setup:
Cabal EU Client
Yamachi updates
CentOS 4.7 Ready to run

Any idea why this might be happening?

EDIT: I also get alot of erros in WorldSvr_01 log files:

[Mon Oct 26 2009 22:54:55.216624 2969312160]: [##ERROR##] AdjustTilePos(Mob:20A0022) Tile(-2:1) species(907), Cur(78:230), To(91:223)

Well firstly even Yamachi says his updates are known to cause problems and advises not to use them.

It could be that there is some lag and the server is getting behind a bit and then suddenly jumping back up to date but that is a total guess. I have not heard of anything similar before and overloaded servers are the cause of some stuff like that (cooltimes acting up too).

The last one is due to some inconsistencies between the client maps and the server map data. It shouldn't cause any problems but the patches posted by Lost-Spirit in the releases section fix most of them. That probably won't help you with your patch though.

Well i stoped using the start-cabal.bat to start cabal and it seems to be fine now. I might just stop using the update because i have some friends that want to connect and they get way too many errors, but some don't what so ever.
