Zabbix stops monitoring for ~10 minutes

[konstantin.lukosko]

Hi,

We have found an interesting issue, at our site.
Every day from 12:09 for approximately 10 minutes Zabbix server don't receive any information. Empy spaces in all pings, processors load or any other items.
Checked the server log, just no any events in this 10 minutes.

How could it solved, because triggers that are configured as nodata(*) are turning ON all the time and it's not good.

Server version - 1.6.4

Hi Konstantin,

Are u doing a database backup or server backup during that time?? I had the same problem due to a daily backup of our db, which locks some tables and thus locks hte processing of the zabbix server!

Some other thing going on on thsi server ( regulary basis??) Check cron ??

greets

Thanks, for the help,

Checked backups or crontabs - no luck.

Have started to write log for mysql server. Found that at this time, the only activity that happens in this 10 minutes are such blocks:

090527 12:12:52 1235 Connect zabbix@localhost on zabbixzone
1235 Init DB zabbixzone
1235 Query SET CHARACTER SET utf8
1235 Quit
9 Query select escalationid,actionid,triggerid,eventid,r_eventid, esc_step,status from escalations where status in (0,1) and nextcheck<=1243415572 and escalationid between 000000000000000 and 099999999999999
090527 12:12:55 9 Query select escalationid,actionid,triggerid,eventid,r_eventid, esc_step,status from escalations where status in (0,1) and nextcheck<=1243415572 and escalationid between 000000000000000 and 099999999999999
090527 12:12:58 9 Query select escalationid,actionid,triggerid,eventid,r_eventid, esc_step,status from escalations where status in (0,1) and nextcheck<=1243415572 and escalationid between 000000000000000 and 099999999999999
090527 12:13:01 9 Query select

And nothing else.
The only idea that I have is to create a test Zabbix server and copy a database to it to see what will happen at this time.


Maybe some one have met the same problem?
