We had an issue in the past with trying to generate a pdf with around 3000 meeting listed. We get a 500 server error. The issue was resolved at one point but now we are experiencing the same issue again.
The pdf is for a state wide printed meeting list that we use for H&I facilities and prison release packages.
The last time it happened I believe you determined it was an issue with overloading the code4recovery servers while generating a pdf from the large amount of data. We're running WP 6.4.3. TSML plugin 3.14.32 on area03.com.
