Sysser error

[zeimpekis9 93]

Hello community. I have a problem. I am at the town with my player, and suddenly i get kicked.
Thats at sysser:
SYSERR: Sep 30 23:56:48 :: Process: UNKNOWN HEADER: 209, LAST HEADER: 0(0), REMAIN BYTES: 15, fd: 21
SYSERR: Oct  1 01:14:49 :: pid_init: 
Start of pid: 5020

Any idea?

[Ikarus_ 3174]

there is a mad packet with header 209 that is unkow for client (omg really?)

search which packet header (in packet.h , type HEADER_GC) have 209 value.

if there'isnt packet HEADER_GC with that value , the question is much difficult to resolve
