Subject: Kernel panic on java mail server

Hello,

I have a stange kernel panic on a zimbra mail server (mysqld + server in
java)... when the java process starts the system freeze...
This is the first time that i have that kind of problem over 70 same
kind servers.

The hardware has been changed 3 times (2 times on AMD server, 1 time on
Intel server).

I join the traces on the intel platform, Tyan S7012 MB, 1 CPU Intel
E5645, 48GB RAM, kernels 2.6.32.41 and 2.6.39.1 without debugging
enabled and the output with the 2.6.32.41 with debugging enabled.

It was tested on 2.6.32.41 / 2.6.35.13 / 2.6.38.4 / 2.6.38.8 /
2.6.39.1.... same thing.

Thanks for helping.
Yohan

Tested on 3.0.0-rc3 without debugging but with profiling, SECCOMP and
CC_STACKPROTECTOR : when starting the java process, the OS reboot
without any error message on the serial console.
