I have a Zabbix 1.8.4 server configured to check ICMP ping latency to several hosts on the LAN using a simple check icmppingsec[,5,300,,300,avg]. The latency grows over time until the Zabbix server is rebooted. (see attached latency graph) After the Zabbix server is rebooted, the latency drops back down to sub-millisecond. I have verified that fping and ping from a command line on the Zabbix server show the same results as the graph.
However, pings from the monitored hosts to the Zabbix server show normal latency at the time the Zabbix server is showing high latency from itself to the monitored hosts. The server and monitored hosts are all connected to the same Dell 24 port gigabit switch.
Granted this may not be a Zabbix issue, but the problem is only with the Zabbix server and not any other host. Any idea what could be causing this growth in latency?
Zabbix server is running CentOS 5.5
uname -a shows: Linux 2.6.18-194.32.1.el5 #1 SMP Wed Jan 5 17:53:09 EST 2011 i686 athlon i386 GNU/Linux
