RTMP publish issue

I have this application that connects to an AMS instance over RTMP and, using NetStream.publish, I stream a video to the server for storage and playback.

99% of the time this works, but every so often, a video will be saved with a size of 15KB or less. These videos are corrupted and cannot be played back.

Then, suddenly, none of the videos would stream properly, and they all kept coming out with a size of 1KB. I had to restart the server, and the issue cleared up. All users could get Net.Connection.Success events, so they could connect to the server just fine, they just couldn't stream their videos to the server.

Why does this happen? How can I stop it?

I'm working with Adobe Media Server 5.3
