Hello all.
I have some zones (zones also Solaris 11) on Solaris 11. Inside this zones runnig nginx+php-fpm (php 5.4.3). Time by time php-fpm drop down with messages "Stopping because process dumped core". coredump is enabled:

# coreadm
     global core file pattern: /var/cores/%d_%f.%p.%n
     global core file content: all
       init core file pattern: core
       init core file content: default
            global core dumps: enabled
       per-process core dumps: enabled
      global setid core dumps: disabled
 per-process setid core dumps: disabled
     global core dump logging: disabled

but nothing created. So, i decide to use dtrace to examine the problem - why php-fpm is drop down?
Can you help me, how to use dtrace to solve this problem?
My experience with DTrace is very small.
Thanks.
