Server Error: Unable to establish loopback connection

Hi.

I'm having a trouble with Wowza Media Server 2.2.4.07.

First, after the server machine turn on, Wowza works fine, but after about 3 days, media content and administration port doesn't work. Access and error logs generates the following message:

java.io.IOException: Unable to establish loopback connection

Second, I try to restart service, but without luck. Error log generate, in addition of above, the following messages:

Third, when the problem is occurring, to check tcp connections of the server, I use the command line "netstat -s" and note that "TCP Statistics for IPv4 -> Current Connections" has a low value (about 60)

Fourth, I also have tried this post's solution, adjusting TcpTimedWaitDelay to 30, and I've tried too this another post's solution.

Both attemps without luck.

PS.: Running in Windows Server 2003 R2 x64, java 7 u25

Thanks in advance.
