Hi All

I've just bootstrapped my new, shining puppet setup (replacing an 2,5  
year old, messy one), with (almost) all the bells and whistles: A  
Passenger-based setup with storeconfigs enabled.

For a start I've only got three node definitions; two specific ones  
and node default. The default one doesn't do anything yet, and only  
one of the specific nodes has actual classes enabled.

Now, when I startup mysql and puppetmasterd, the first one or two runs  
of puppetd on the client is fine. Puppetmasterd stores the configs,  
but suddenly (and this is with only one host contacting the  
puppetmaster) the log says:

Could not store configs: Mysql::Error: MySQL server has gone away:  
SELECT * FROM `hosts`   WHERE (`hosts`.`name` = 'web01.mydomain.com')   
LIMIT 1

At first I thought it was MySQL drowning, but I've found that a  
restart of puppetmasterd (with /etc/init.d/apache2 restart, as it run  
through Passenger) fixes the problem - but only temporarily. Next time  
a host contacts the puppetmaster, I get the error stated above. :- 
( And it fails until I restart puppetmaster again.

I have the following optimizations in my passenger configuration (cut  
from Nigel Kerstens mails about his Passengerbased setup):

PassengerLogLevel 1
PassengerMaxRequests 3000
PassengerMaxPoolSize 15
PassengerStatThrottleRate 600

I've also tried to optimize the MySQL configuration, but as a restart  
of Apache/Passenger solves the problem (for one clientrun), I don't  
think that the problem lies with MySQL.

Do any of you have a clue of what can be wrong here?
