Hi,

We have a Zabbix server installed on an EC2 instance in AWS. The Zabbix server is installed on a t2.large (2 vCPU and 8GB RAM) EC2 instance.
We have installed MySQL on the same server. We have noticed that the memory usage of the server keeps increasing day by day.
The Zabbix server currently monitors 60 Hosts.
We have attached the memory Utilization graph. Could you please throw some light on this issue?
The version of zabbix is:
zabbix_server (Zabbix) 3.2.1
Revision 62890 30 September 2016, compilation time: Oct 3 2016 04:57:19

We did not find this version when we tried to raise a ticket, hence we selected 3.2.5.
We are not sure if this is a bug.Please do let us know if you require any additional information to assist us with this issue.
Thanks in advance!
