my problem is that when i amkilling monsters, it dc's me,
or any elsf ppl, the one that attacking and killing gets dc.
when i saw the Gs log , it said the gs send logout.
i checked on google the problem, and i found that the gs is shows up when too much data is sent to the GS, thats causes the DC

How do i fix it.
