Using Zen-cart v1.3.9e for some time with no issues. However over the last few days some of the order confirmation emails have not arrived. All the corresponding PayPal notifications have arrived.
All orders are listed when checking ZenCart Admin -->Customers-->Orders.
I sent 10 consecutive emails to the address used for order confirmations and all arrived quickly with no issues. So it would seem the issue is the creation or sending process is failing from time to time.
I checked the log files and no warnings are posted.

Any ideas?
