StackOverflow when running Puppet agent -t

[Med75]

Hi all,

I'm getting the floowing error when I run Puppet agent -t

[...]
Finished catalog run in 209.01 seconds
Error: Could not send report: Could not render to yaml: Stack overflow in regexp matcher: /\A(?: # ?: non-capturing group (grouping with no back references)

I'm running Puppet 3.0.1 on server and client and both are under Amazon Linux (compatible Centos). 

Here is my master's Puppet.conf : http://pastebin.com/CpbXbuuK ...and the client Puppet.conf :http://pastebin.com/irs20s7Y

Do you have any idea of what it is and how to solve it ? Thank you !

Could you please run the agent with the --trace --verbose --debug
options turned on and then paste the complete stack trace that results
in this error? This information will help me diagnose this further.

Thanks,

The problem disappeared after a reboot of the client. I saw your answer too late so I haven't had the chance to run the agent with --debug and --trace... I'll update this thread once it will be back again.

meanwhile, and after a couple of agent run, I'm now getting a different message, here is the full stack trace: http://pastebin.com/yLdBhcyN

I don't know if this is related or not, and if it would be better to create a new thread.

Thanks!

How much memory does the machine have, and how much memory free? It
looks like the system is running dry:

Cannot allocate memory - fork

FYI, In Puppet 3 we're now using fork when doing catalog runs, which
may increase memory utilization relative to previous versions of
Puppet.

the system still have free memory, here is what get when I run free command:

                   total       used           free       shared    buffers     cached

Mem:        609600     455840     153760          0       1256     105236

-/+ buffers/cache:     349348     260252

Swap:            0          0          0
