Too many open files / can't identify protocol

    Details

      Description

      My Zabbix Notifications gone wild, because all my items started flapping between "Not Supported" and "Normal".

      After pinpointing the problem, I've seen that there are too many open file descriptors on all my zabbix agents:

      open file descriptors
      root@moros:~# lsof | grep zabbix | wc -l
      3184
      root@moros:~# lsof | grep zabbix | more

      I'm using *Zabbix Agent 2.4.3-1* on Debian 7.7:

      I'm using a *Zabbix MySQL Proxy version 2.4.3-1* as well on Debian 7.7.
      The *Server is version 2.4.3-1* and is also running on Debian 7.7.

      That never happened before / in the older versions.
