# You may specify the path to the FastCGI crash log (a log of unhandled
# exceptions which forced the FastCGI instance to exit, great for debugging)
# and the number of requests to process before running garbage collection.
#
# By default, the FastCGI crash log is RAILS_ROOT/log/fastcgi.crash.log
# and the GC period is nil (turned off).  A reasonable number of requests
# could range from 10-100 depending on the memory footprint of your app.
#
# Example:
#   # Default log path, normal GC behavior.
#   RailsFCGIHandler.process!
#
#   # Default log path, 50 requests between GC.
#   RailsFCGIHandler.process! nil, 50
#
#   # Custom log path, normal GC behavior.
#   RailsFCGIHandler.process! '/var/log/myapp_fcgi_crash.log'
