Issue with nginx crashing 'segfault'

experiencing.

Basically, the nginx workers are crashing intermittently causing our
application no server requests.  We are using nginx with mod_security and
mod_passenger. Apparently, this may be related to mod_security but can
somebody shed some light as to how to solve it ? Is there a fix in the
nginx code base or mod_security code base ?

Thanks,
Ricardo
