Plain Text dashboards returning Unexpected server error when trying to edit on v7.0.0

[KaloyanHr]

Hello,

After upgrading Zabbix from v6.4.7 to v7.0.0, I cannot edit any of my past plain text dashboards (which should now be item history as per https://www.zabbix.com/documentation...n-text-widgets), I get directly Unexpected server error. I tried also recreating the dashboard but when I choose the item in Columns and click add, I get immediately the same error. also checked the zabbix server logs but there's nothing there regarding this. Can you please advise if there's any way to fix this ? I

Thank you

Hello,

I have got the same problem. Item history widget returned "Unexpected server error". And after looking into webserver log i found error like:

FastCGI sent in stderr: "PHP message: PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /var/www/include/classes/api/CRelationMap.php on line 72" while reading response header from upstream, client: 10.10.42.253, server: zabbixapp, request: "POST /zabbix.php?action=widget.itemhistory.edit HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/www.sock:", host: "zabbixapp", referrer: "https://zabbixapp/zabbix.php?action=dashboard.view&dashboardid=2&fro m=now%2Fd&to=now"

Similar problem solution here: https://www.zabbix.com/forum/zabbix-...ed-to-allocate

Though i am not good at web server administration and there could be problems like memory leak or something like that(which is mentioned in comments to this kind of problem solving)

I use nginx as webserver so i needed to change file
/etc/php-fpm.d/www.conf

php_admin_value[memory_limit] = 128M
to
php_admin_value[memory_limit] = 256M

restart php and nginx
