Is there a maximum number of global macros allowed

[lmnti33s]

We are on Zabbix 7.0.17 LTS and we have just tried to add a global macro (we apparently already have 200) and when we click save to add, the interface says it was successfully added by the item is never added to the database table and a refresh of the global macro page shows it is not there. Is there some limit on the number of global macros you can have and/or, if so, is that configurable?

So finally discovered that the cause of this was that we did not have PHP max_input_vars set so it was defaulting to 1000. 200 macros*5 posts per macro=1000 is my guess. Setting this to 10000 and restarting allowed us to start adding more than 200 macros
