/var/log/httpd/error_log on the APS application endpoint server fails:
[Tue Oct 24 18:01:25.452317 2017] [:error] [pid 12818] [client 192.0.2.2:33274] PHP Fatal error: Maximum execution time of 30 seconds exceeded in /usr/share/aps/php/aps/2/apsc.php on line 357
Cause
The default PHP maximum execution timeout configured on the endpoint node is not enough for the operation.
Resolution
Edit /etc/php.ini and set a larger timeout
max_execution_timeout = 120
Reload Apache service:
# service httpd reload
