Zabbix 3.2 portal intermittent issues

[sathiya]

Hi All,

Zabbix 3.2 portal has some intermittent issues, all the services running ok but the portal throws error message while clicking on one tab from other.
It loads for a while and says "This site can’t be reached", please find few logs below and let me know if you need more logs to analyse the issue.

Hi,
Which site can't be reached and why you've pasted ps output? The GUI (Frontend, WEBUI, etc) is a PHP-based webpage and utilizes apache(by default) engine. So if you see errors with the Frontend - try to digg the apache logs and check the firewall.

Also it is very useful to now what was changed before the issue appeared for the first time

Regards,
Alex!

Hi Alex,

Thanks, we didn't do much changes apart from setting some email alerts.
Initially we thought it might be the issue with RAM hence we increased the RAM and checked but no change.

But the issue seems to be with chrome since it is working fine with IE 11, but it was working with chrome as well till last week. What might be the reason do you think?
There were no major changes took place during the weekend.

Have you tried to look into the Apache error logs?

Alex!
