panic on 5.4 SMP kernel when jailed apache is used heavily

Hi all,


I upgraded a 5.3 system to 5.4 both with SMP kernels, I'm running 6 jails on
a dual xeon 1.26 hp rackmount. When apache (both 1.3 and 2.0) is being used
heavily the system panics. With a 5.4 GENERIC kernel or a 5.3 SMP kernel
this behaviour does not happen and the system is stable. Does anyone have an
idea ? Or should I post this to bugs ?
