JVM exited unexpectedly

Hi everybody,

I have a problem starting the Netflow Analyzer. It fails to start the mysql Server

I made a kernel update of my NFA 7 server (CentOS 4.6, kernel 2.6.9-67.0.15 to 2.6.9-67.0.22) and after the reboot, I had this error "Trying to start MySQL server failed; JVM exited unexpectedly."
I came back to the old kernel but it doesn't solve the problem.

If I use the the "startDB.sh", it's OK
same thing with the run.sh

(My mysql-ds.xml was already with 127.0.0.1)

Have you any idea of of the problem ?

Thanks
