Unexpected "Exiting normally" 2.1.8?

Wed Nov 4 18:26:22 CET 2009

Hi Alexander.

  Thanks for the update - I was concluding I'd have to wait for the release 
of 2.1.8 to pursue this.  I am currently in a situation where I can help 
debug 2.1.8, since the 'new' systems aren't yet in production.

Looking at your debug output (and I am in no way an expert at that) it seems 
as though the process received a signal?
I am running a 'custom' module (event.c as I recall) from Alan that resolves 
an issue with hung children (very exciting!), and I followed Alan's 
instructions to get to this point.  I would really like to try to 'give 
back' if I can and assist in identifying the cause of the program exiting 
(assuming it is a new and as of yet unidentified bug).

Would copying the steps you have below on my two redhat systems be a good 
way to proceed?

Let me know,
-craig
