I'm getting a lot of 'connection reset' errors all of a sudden on our
0.24.8 puppetmaster.
I'm assuming that's a load issue?
Probably, I had the same problem recently and solved it by serializing
puppetd runs. It works by restarting my puppetd processes daily at a
host-specific time from cron:
- have a sorted list of all nodes accessing your puppetmaster
- external node classifier computes rank of node (the host's place in
above list) modulo 30 and puts it into a parameter
- install cronjob on each machine to restart puppet daily at some hour
and rank minute
It's not perfect, but instead of load spikes up to 10 for several
minutes, the load on my puppetmaster stays between 0.5 and 1.
It would be really nice, if puppetmaster had some intelligence, to
help spreading out clients like this automatically.
There is --splay
