Our three HP Procurve 1810-24GE-Switches are kinda weird. First I noticed in Zabbix that we have high ping spikes (up to max. 200ms) on all the three switches every 3 minutes. An example:
At exactly 1:00:40 the spike starts. The peak is nearly always exactly one minute later (1:01:40). Exactly another minute later its back to normal again (1:02:40) and after another EXACTLY 2 minutes it all starts again (1:04:40).
So there has to be some task or so that is blocking my pings or smth like that, right? Any idea what it could be? Exactly these three switches are also the same that do not provide any data to my Zabbix graphs besides the "Ping" and the "Ping response time"
