<div>It sounds like you just have high-bandwidth streams:</div>
<div><br></div>
<blockquote type="cite" cite><font face="Courier New"
size="-1"><b>PS</b>. These logs captured while recording 16 mjpeg
streams (each with 20 FPS and 32KB framesize)</font></blockquote>
<div><br></div>
<div>That's almost 82 Mbps. Are you sure you have sufficient
network capacity for this (i.e., you don't just have 100 Mbps
Ethernet, which would not be sufficient)?</div>
<div><br></div>
<div>If your problem is packet loss (but you have sufficient network
capacity), then you need to increase your OS's buffer size for
incoming network packets. See
