Hi,
Zabbix (v1.0) often detects that our smtp, pop and imap services are down (thus sends alerts) but they're said to be up again in a minute. I don't know why they are said to be down.
Those services are running on the same Linux host. The smtp service is provided by Postfix, while the pop and imap services by Cyrus. When they're said to be down, the CPU load is not high (eg, processor queue length < 1.5) and there's quite some free RAM (eg, > 90MB free). Sometimes two services are said to be down at roughly the same time, but it is possible that only one is said to be down.
I've set their polling intervals 60, 61 and 62 respectively to prevent polling them at the same time. I've configured to preload an idle process of pop and imap. However, this is still happening.
We're using Zabbix to monitor quite several hosts. Only this one has this kind of problem. This one has the highest CPU load and the least free RAM.
Any idea? Thanks in advance!
