please read below.probably give you help.

HotSpot uses SIGSEGV internally. It does on x86 too, but the x86
kernel doesn't have a segfault logger, so you don't get these messages
there. IIRC there's no way to disable the x86_64 segfault logger
without recompiling the kernel.

Oh and when is 1.4.2 64-bit final coming out ?

there is a problem with your kernel

在官方wiki上看到了一句话。
Changes with nginx 0.6.32
Bugfix: a segmentation fault might occur in worker process on Linux, if keepalive was enable
我升级一下nginx在看看
