Cod WW: 1024 bytes Command Exploit

[Jumping Jack Flash]

Hi guys, every day my cod5 server fall down cause this error: Attempted to
overrun string in call to va()
I've found some information about it:

"va() is a function of the Quake 3 engine used to quickly build strings
using snprintf and a static destination buffer.
If the generated string is longer than the available buffer the server
shows an "Attempted to overrun string in call to va()" error and
terminates.
