PuppetServer 2.8 resource Leak


We have PuppetServer 2.8 on RHEL7.

After some days computation of the catalog become slower and slower; the
load average of the compute nodes increased and the compute goes in timeout.

All our 4 computes nodes have 48 cores, only 10% of each core is used
when the timeout occured.

We are on hiera v3, we only tuned “max-requests-per-instance: 5000”
because of a databases connection leak with our Trocla library.

Only 150 nodes are connected to our PuppetServer.

We never had this problem with [urlhttps://goo.gl/nY47NM]Puppet[/url]3 (with more than 3000 nodes)

Anyone have already see this or have a tips to resolv this ?
