    It looks like you are hitting the 4GB file size limit of FAT32 file systems. See if you can upgrade to NTFS.

    As I understand it, you would do better with RAID 0 or 1+0. With RAID 5 you are writing the same file to at least two disks. You could achieve parity by making a copy of each file after it is recorded using this method:

    No need to be rude. Actually I have very little personal experience with RAID arrays, but we do recommend RAID 0 or 1+0 for use with Wowza for performance reasons, and I was passing that information to you. In any case, I don't think it is a Wowza problem. It seems more likely a hardware problem, but if you can reproduce it (on a single disk) and tell us how to, we can see if there is problem that can be patched.

    I am so sorry!!! I am not rude! I just want to fix my problem! I have some little experience with RAID, and with RAID5 i will have good performance for record many streams and read files for many customers at the same time. For server RAID5 array is as one phisikal disk, i have 10 disks x 2TB in that array
    Now i am record 20 streams from multicast on this array over rtpdump, and it work, so i dont think that it is problem with hardware

    I have test server with trial license of wowza and one 500GB hard drive, ofcource before i have try live stream record there, it was the same problem

    Lelik,

    Are you saying you are able to record over 4GB with VLC and rtpdump?

    Maybe Wowza cannot record files greater than that. I'm looking in to that. Maybe some other aspect has a 32-bit limit, like flash or a module. Can you provide more info about your setup? List how you're doing your encoding, modules, type of client, etc..

    Also, what is your Wowza version? Be sure to upgrade to the latest version. This issue may have been addressed.

    Yes, i can record files by rtpdump and vlc over 4GB, but anyway, my recorded files is around 700MB for each hour, it is normal for my streams
    I am transcoding multicast channels by VLC to h264/AAC , and send that streams to wowza, wowza setuped to streaming rtmp and cupertino, and i have setup application Livestream record for recording rtmp streams from wowza
    That is my version #Software: Wowza Media Server 3.0.3.10 build995
