appearant puppetserver memory leak

[Michael Eklund]

We are running puppetserver 1.1.3 under Ubuntu Trusty.  It is apparent that we have a memory leak of some sort.  Tuning guide claims ~512M of ram per instance, we are running with max-active-instances: 8, and I have gone from xmx5G to xmx12G yet the memory graph continues to look like this: https://www.evernote.com/l/APfJL68nnJpDf6cova5wopm-6cS2_W7T6yU

I saw in the release notes for 1.1.3 that there was a leak when using max-requests-per-instance which some folks were ironically using to deal with module code that has memory leaks.  We are not currently using  max-requests-per-instance.  I would like some guidance in trying to determine if there is a buggy module, and if so which one or ones are causing the memory leak.

Thanks,
