FC2 mod_jk2 and Apache vulnerability

[C.F. Scheidecker Antunes]

Hello,

I've got the lattest mod_j2k and Apache on my FC2. From the last two 
days the server is going down and I am having a weird message on the log 
regarding mod_jk2.

I have a buch of errors and weird atempts and them mod_jk2 shuts down.

This is smelling like an invasion attempt caused by a vulnerability.

Can anyone comment on that?

Are they known issues for mod_jk2 4.1.27-13 or Apache 2.0.51-2.7 ?

Thanks.
