You can disable parallel fact resolution with facter.conf 
(https://puppet.com/docs/facter/3.11/configuring_facter.html 
) by adding



global : {

sequential: true

}


That helps, yes.

The system is a VM on OpenVZ. Other machines on Hyper-V and VMWare are 
not affected.

Re: [Puppet Users] Could not retrieve local facts: can't create Thread: Resource temporarily unavailable

[Bogdan Irimie]

Hi Helmut,

Facter 4 resolves each fact on a separate thread, this can lead to a high
number of threads being created. Can you please provide the output of `cat
/proc/sys/kernel/threads-max` on the system where you see this issue? Does
this happen at every run or sporadically?

Please try to run facter from the cli and let me know if you have any
issues.



You can disable parallel fact resolution with facter.conf (
https://puppet.com/docs/facter/3.11/configuring_facter.html) by adding


global : {

sequential  : true

}



Best regards,

Bogdan Irimie
