    Description

      Steps to reproduce

      proc.num seems to have an issue with long process IDs on the latest Ubuntu LTS Release.

       

      On Ubuntu 18.04 the check gives the correct result:

      # zabbix_agentd -t proc.num[fail2ban-server]
      proc.num[fail2ban-server] [u|1]
      # ps wax |grep fail2ban
      590 ? Ssl 207:44 /usr/bin/python3 /usr/bin/fail2ban-server -xf start
      

       

      Same check on Ubuntu 20.04 gives:

      zabbix_agentd -t proc.num[fail2ban-server]
      proc.num[fail2ban-server] [u|0]
      # ps wax |grep fail2ban
      3446386 ? Ssl 93:28 /usr/bin/python3 /usr/bin/fail2ban-server -xf start
      
      

      Root cause seems to be a change in /proc/sys/kernel/pid_max:

      On Ubuntu 18.04 it's 32768, in Ubuntu 20.04 it's 4194304. Looks like Zabbix Agent has an issue with bigger PIDs.
