Thank you for the update. The PHP max_execution_time on our servers is 120 seconds and should be more than enough for the execution of any single PHP script. However, we have timeout limitation of 30 seconds in the webservice which is a regular value with most hosting provider’s. In any situation, I was able to trace the errors that you were receiving:

and they are indeed caused by the Timeout limitation of the webservice. I went ahead and increased this value to 300 seconds for all scripts that were experiencing such timeouts. In case the script timeouts again, this would mean that the PHP max_execution_time value of 120 seconds is being reached. I am afraid that the PHP max_execution_time could not be increased further on our shared hosting servers and in case the process continues to timeout, I would recommend you to consider reducing the batch sizes to appropriate value that would suit the current limitations.
