Zabbix 5.4.2 problems

[LdeB]

I have an old Zabbix 4.0 server with proxies and never given me any problems except a couple of GUI bugs which are well known.

So installed Zabbix 5.4.2 on a new server and it was relatively painless but it has a weird problem where the graphs don't update. When you go to edit the graphs the data is there but the normal view is not the same.

To add to that I gave the system a remote proxy and that will run for 20-30 min and then stop with this message

zabbix_proxy [87]: Error waiting for process with PID 356: [10] No child processes
87:20210709:145634.071 Zabbix Proxy stopped. Zabbix 5.4.2 (revision 4c8f9aabe1).

So the basic question have I been unlucky or is Zabbix 5.4.2 unstable and if so what version should I be using.

Regarding the graphs not updating, you can vote for this issue: https://support.zabbix.com/browse/ZBX-19419
Note you can also override the dashboard default with a custom "Time period" where To equals "now", but that of course makes the dashboard time-range settings useless...

I'm constantly searching on the internet for posts that will help me.

If the OpenBSD operating system is used, a use-after-free bug in the Net-SNMP library up to the 5.7.3 version can cause a crash of Zabbix server if the SourceIP parameter is set in the Zabbix server configuration file. As a workaround, please do not set the SourceIP parameter. The same problem applies also for Linux, but it does not cause Zabbix server to stop working. A local patch for the net-snmp package on OpenBSD was applied and will be released with OpenBSD 6.3.
