In my zabbix server it logs as
# sudo tail -f /var/log/zabbix/zabbix_server.log
housekeeper [deleted 105926 hist/trends, 0 items, 0 events, 0 sessions, 0 alarms, 0 audit items in 3.718012 sec, idle for 1 hour(s)]
and after this it fails to send the Alerts
5243:20171213:180658.517 Failed sending data to the peer: DATA failed: 550
5243:20171213:180702.182 Failed sending data to the peer: DATA failed: 550
5243:20171213:180705.812 Failed sending data to the peer: DATA failed: 550
Can you help me why this occurs and give me a solution
I solved this
Beacuase i have configured email to a person in more numbers in the sense
user will get more than 3 alerts for a problem and a ok alert and reduced
the alerts to single alert fro problem per person.
when the **zabbix alerter process exceeds 75%** this errors occurs
Zabbix alerter processes more than 75% busy
and zabbix is not able to send alerts to all peer hosts
