I'm selling a 2.5 GB video in my store. Some customers with slow internet connections are seeing the download stop before it's complete. For example, a customer with a 1.2 Mbps (150 KBps) connection speed had his download stop before it even reached 100 MB.
I throttled my connection speed via my firewall, and I can reproduce this problem. I'm not sure if it's specific to CS-Cart or if it's an Apache or PHP configuration issue.
Any suggestions to troubleshoot and correct this?
Apache 2.0.64 / PHP 5.2.17
