I was trying to generate one csv file dynamically for each recipient in AC server for the group of recipients.
After that tried to deliver the email to the group of 700+ people and attached this generated csv files. Then I face the following error for 70+ people out of 700+ ..
"Cannot open file '<file name>' with read access (errno=2, No such file or directory)"
But actually csv files are there for this 70+ people also. When the delivery job retried again after 1 hour later it was successfully go through for this 70+ people. Any idea why the error happen on first attempt? The file size is not more than 1 MB for each file.
Thanks for your reply. I tried to check the pattern but I don't find anything. But I have noticed that only the first few are fail for first one minute when I check the last modified date. After that the rest are all go through. And other batches with less than 100 recipients are always successfully go through.
I created 2 batches of 700+ email for 2 different months. In both deliveries, the first delivery attempt was fail for few recipients. Both times only go through 600+ but not the exact number. First time was 690+ and 2nd time was 630+.
I don't understand why for those 700+ deliveries, the recipients that are processed within first 1 minutes are always fail. And it only happens for this 700+ recipients batches.
