Hello,

Today some char 'did' something, which was stored in DB, which made a huge cpu usage jump of java processes.

In game it looks like this:

Attack on super haste is not continous but like in a packages 2..4 hits, then little break, and few hits again. After some time (sometimes 1 sec, sometimes 20 sec) meele attack is getting stuck, and I cant repeat it anymore unless I change location - then the story loops and again I'm able to attack for short time, and stuck again... 

The server load looks like this:

As you can see load jumps up around 1:30 AM. There was nothing unusual happend at that time.


For now, the only solution I've found is to remove chars that were logged since around 1AM. It solves the problem and attack is normal again (without stucking, without 'packages'). However its 2nd time I'm affected with it and it would be nice to find the real cause :)

Any advice?

Best regards!

Magically fixed by itself at ~20:15. After few hours of high load and planty of restarts (which none of'em did actually helped).

Whats goin on? Any ideas?
