    Description

      Steps to reproduce:

      1. Create Zabbix agent(active) item with a scheduled update interval.

      Result:

      1. Item becomes not supported as expected (Incorrect update interval).
      2. Zabbix agent log is constantly reporting this issue:
        16839:20220126:141013.767 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        16839:20220126:141013.767 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        16839:20220126:141013.767 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        16839:20220126:141013.767 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        16839:20220126:141013.768 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        16839:20220126:141013.768 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        16839:20220126:141013.768 active check "system.swap.in[,pages]" is not supported: Incorrect update interval.
        
      1. History cache gets full with values from this item:
        zabbix_server -R diaginfo="historycache"
        == history cache diagnostic information ==
        Items:1 values:1288304 time:0.000893
        
      1. History syncer gets very busy processing all errors reported by item
        13874 ? S 0:00 /usr/sbin/zabbix_server: history syncer #1 [processed 0 values, 0 triggers in 0.000052 sec, idle 1 sec]
        13875 ? S 16:21 /usr/sbin/zabbix_server: history syncer #2 [processed 37609 values, 28 triggers in 11.000972 sec, syncing history]
        13876 ? S 0:00 /usr/sbin/zabbix_server: history syncer #3 [processed 0 values, 0 triggers in 0.000033 sec, idle 1 sec]
        13877 ? S 0:00 /usr/sbin/zabbix_server: history syncer #4 [processed 0 values, 0 triggers in 0.000061 sec, idle 1 sec]
        

      Expected:

      1. Item becomes not supported with correct error message.
      2. Agent log is not filled with millions of entries.
      3. Zabbix server is not processing millions of errors.
