Dear all,
I have an issue with zabbix where it completely freezes when using the zabbix-pdf-report tool (https://github.com/catonrug/zabbix-pdf-report). To give a more detailed description, when I try to generate a PDF report, the whole webui becomes unresponsive (e.g. if I have another zabbix Tab on the browser I can click on the buttons but nothing happens), when the PDF generation process ends, everything goes back to normal. But if this process takes too long (in the order of ~30 seconds) the webui docker seems to hang and never comes back. It happens only when using zabbix with docker containers (zabbix-server-mysql:alpine + zabbix-web-nginx-mysql:alpine both on version 4.4.0). I tried to test it with a Zabbix installation from packages (on Linux Mint 19.1) and everything works perfectly. I guess it has to do with the communication between the two docker containers (server and webui). Perhaps I am missing something on the docker container configuration (didn't do something nasty there, using defaults).I would appreciate any hint that will help me understand what is going on.
Thank you in advance.
