Server "Large Send Offload" causes weird problems

[wjssz]

The server Fire.cn has many weired problems since June of 2013, such as:

• suddenly can't move
• suddenly display XP screen while playing
• scope of sniper gun is black
• wall is transparent
• unlimited bullets
• can't reload bullets
• can't shoot
• pistol disappear
• ....

After disabled "Large Send Offload" of network adapter, the problems disappear.

There is a thread said:

Disabling Large Send Offload may fix that. Ive seen 15k and even 30k packets, regardless of MTU.
