nginx 100% cpu usage

[lalyos]

Hi,

im using nginx 0.8.54 in front of a tomcat. its running since 1 week
now, and with just a few open sessions, nginx is using 100% cpu.

strace is telling that 'munmap' is responsible for 94%. so looks like
some sort of memory problem,
but top shows that 400mb is free from the 4gb total memory.

more detailed logs (strace sample/top/nginx acces/error logs)
https://gist.github.com/3089367

note this is a vmware virtual machine.

any tips?
