Mongrel users - Aug 2006 - running multiple mongrels from same application root - is it safe?

Hi All

I was wondering if I run  multiple mongrels from same application root (one
physical path) on the same machine is it safe as far as logging is
concerned.

I mean won''t there be race conditions or file locks and out of sequence
logging statements?

TIA

I agree with not using print,. puts and p

But what I am trying to understand and missing are

1. If I run multipe mongrels pointing to the same application root
i.e. same folder on one and
only one machine. Is it possible to have logging out of sequence i.e. first
request logged in after second request or worse file locks and deadlocks.

2. On Win2K Sp4 atleas there is no mongrel.log that is ever created. So no
chance of ever catching a catastrophic failure log

After seeing you struggle with this, I suggest you use the built-in
Rails logging facility instead of p, puts, and print.  In any of your
actions you just do:

logger.debug("stuff")

And it shows up in the development.log or production.log.

The mongrel.log is really only for major catastrophe and reporting bugs
to me.

Otherwise, yes they''ll be reasonably maintained but no promises.
