@duncanc, thank you, now with the new settings/changes, things seem to be working, but now I am experiencing the following:
If I process 100 bounces, once it finishes, I cannot run another. I get the below where it seems the process of the previous run hasn’t stopped yet.
phpList - A process for this page is already running and it was still alive 568 seconds ago
UPDATE:
probably I should wait a bit longer since I am sure PHPList is in the middle of processing the data. We can ignore my above observation.
