Running Ubuntu 9.10.
Wowza Media Server 2, patch 9
Java 1.6.0_15

I have had this happen twice. I run /etc/init.d/WowzaMediaServer stop, followed by start and the server doesn't come back up.

When I look in the logfile, it complains about a bind exception with Address already in use. When I check netstat -atp and find that the wowza ports (8083, 8084, 8085, 8086 1935) are all listening but have no process number or name associated with them. A few of them even have active connections with data in the Recv-Q. If I telnet to 1935 it accepts the connection but there is no response. When I check ps, I find a single zombie java process (defunct).

I am not sure how you (or java or linux) have managed to get in that state, but I think it is against the rules. The only thing that seems to fix it is a reboot.

Any ideas?
