Please tell me what do the following messages mean:
1) "Timeout while answering request"
Does the timeout occur when zabbix_server(or proxy) tries to get a value from an agent, which isn't there? Or it can occur at some other points?
2) What exactly do the numbers in the "Queue" section of "Administration" page mean?
If they mean number of checks that are taking [1,5,etc] minutes - what can possibly make a check take such a long time?
3) What does zabbix do when it encounters a lock table wait timeout? Does it retries the transaction?
