We are experiencing a very large memory leak at the moment with out Zabbix 3.2.6 installation. This leak is in the vicinity of gigabytes per hour (see attached graph image).

We have a reasonably large environment (see attached dashboard image)

I am currently taking minute snapshots of all processed on the Centos server and have a script to output any processes that have increased in virtual memory. I have attached a txt file with a 1 hour sample of the top 70 processes increasing in virtual memory which shows zabbix_server being the main processes increasing.
