Steps to reproduce:

1. Use agent
2. Let Poudriere build packages

Remark:

Poudriere on FreeBSD tends to use high CPU, memory and I/O ressources, because it builds multiple packages using multiprocessing. I have enough swap left to make sure processes don't die. Zabbix Agent probably dies, because of the ridiculous amount of memory it wants to allocate (see log).

Result:

Log:

Expected:
Zabbix not allocating a huge amount of memory.
