crash in poller in substitute_lld_macros

    Details

    • Team:

      Sprint 50 (Mar 2019)

      Description

      Steps to reproduce:

      Create calculated item for network interfaces on sub-template that is connected to 100 templates that are connect with 1300+ hosts.

      Everything works when I make "soft" unlink of template on one host and then create the same item on hosts LLD. But when I create the same item on production template - Zabbix crashes.

      Please check screenshot of problematic item prototype:

      Cleaned debug with level 4:
