Title: Memory leak or not?
Post by: droumanet on January 16, 2026, 07:16:14 PM
Hi there,

I manage my firewall with Zabbix since few days, because having lot of trouble (many crashes) on my OPNsense firewall. Well, after two days, it seems there is a memory leak, but maybe, the firewall will update it processes and release all the memory?
Are some of you able to share same graph to see the health of our firewalls? Datas are coming from Zabbix agent.
